"endPeerConnection()" removes the item from the list, so neither a
for-each loop nor an iterator can be used to traverse the list (as a
"ConcurrentModificationException" would be thrown). To solve that now
the list of connections is first traversed to get all the sessions, and
then the list of sessions is traversed to end the connections.

The call activity unregisters from the event bus events when stopped.
However, when the call activity is being closed the new activity can
start before the call activity is stopped; if the new activity causes
new signaling messages to be sent those messages were handled by the
call activity too.
The chat controller joins the conversation again when it is attached,
and the call activity automatically joins the call when it receives a
"roomJoined" event. Due to all that, when the call activity was closed
and the chat controller was opened the call was joined again (and then
left once the call activity was finally destroyed).

If the local participant leaves the call the participant list will be
updated with the new call flags. However, that does not necessarily mean
that a moderator ended the call; the call could have been left too by
the Android app due to a forced reconnection or a time out when starting
the call. In those cases the call activity should be kept open, and only
when the local participant left the call due to a remote action the call
activity should be closed.

When the view is shutting down the call is always left, so the status
should be accordingly set.

As the participants that are not connected yet are clearly marked as
such now the participants are shown as soon as they are found rather
than waiting for a connection to be established.
There is a drawback, however; if a participant will never have a
connection (for example, if the HPB is used and that participant does
not have publishing permissions) the participant will be endlessly shown
with the progress bar. Nevertheless, before they were not shown at all,
which was probably even more puzzling.

Note that this still notifies a data set change if the properties are
set to the same value that they had already, but at least it is not
notified when no data was actually changed.

The local stream is set only when the activity is created. However, it
was disposed when hanging up, which happens not only when closing the
activity, but also in cases in which the call activity is kept open and
the participant reconnects to the call (for example, when starting the
call times out), which caused the local stream to freeze. Now the local
stream is disposed only when the call activity is destroyed.

When a publisher fails during a call a reconnection is triggered, which
first leaves the call and then initiates it again. Initiating a video
call first request the permissions, but it seems that the request hangs
when done while in PiP mode. Due to this if the publisher fails while in
PiP mode and the call is initiated again the call will be simply left,
without reconnecting to it.
The problem is specific to video calls, as in voice only calls
"onMicrophoneClick" is used instead, and it explicitly checks if the
permissions are already granted. Checking if the permissions are already
granted before requesting them is also recommended in the Android
developer guide, and as the permissions are requested during the
original call initialization it is expected that they will be already
granted if the call is changed to PiP mode, so the problem is work
arounded that way (but if the permissions are not granted when the
publisher fails in PiP mode the problem would still happen, although
that should be quite uncommon).

When coming back from PiP mode the self video occupied the full height
of the window. Now the height is set to the default value set in the
layout, so it matches the size used when starting the call activity.
