fixups and refactoring for sharing by context menu

When sharing a file by context menu that is not downloaded yet, do not open it after download but just share it. This is done by 'openWhenDownloaded' variable in chatMessage.

Pass a method to downloadFileToCache, so it's more flexible what to do when download finished.

Add some minor changes
