Debug video room link in side panel

[mariobehling]

The switch between rooms and languages does not always work as expected. When I am in room 324 and listen to Spanish and then directly click on room 325 the audio of room 324 stays and only the video feed changes. At the same time it often happens that the video got stuck and no longer moves forward (though not paused).

Expected: Even if I am on a translation audio stream and the video of one room (e.g. 324) clicking on another room (e.g. 325) should bring me to the other rooms audio and video.
