Split call participants and peer connections

Browse Source 
Instead of trying to create a video peer connection for any joined
participant now only a call participant is created for any joined
participant, and a video peer connection is created only for those
participants that are publishing audio or video.

If a call participants does not have a video peer connection the call
participant is now seen as "connected" from the UI, as there is no need
to show a progress bar for that participant.
