When video/audio is disabled or was failing, there is no hint

[adbenitez]

when video is disabled there is no feedback for the receiver but a black screen, would be better to display the crossed-out camera icon in the center of the black video in the self-preview, and also for the receiver side or switch to the avatar

moreover, for a nicer layout, the then black video screen should be surrounded by a dark black border.

in the case of the audio a crossed-out mic icon should be shown in a corner of the video

esp. for video, this should be displayed on both sides, but for simplicity, also audio should be displayed on both sides

this is now even more important, as we will likely have video disabled by default

As @Amzd mentioned, setting enabled = false on local side doesn't set muted = false on the remote site.

I just tested the replaceTrack() approach from #50 (comment), and this is what affects the muted state of the track. The following's value flips as the remote side switches the video on and off:

__callsManager.peerConnection.getTransceivers()[1].receiver.track.muted

I think that this would be the proper way to detect whether the other party has video disabled, as well as the proper way to fix #50.

#13 is the way to show the avatar and self video together, but it's closed.
