Stopping a cloned MediaStream video track should not stop any other video track
https://bugs.webkit.org/show_bug.cgi?id=199635

Reviewed by Eric Carlson.

Source/WebCore:

In case a track is requesting its source to end, the
RealtimeVideoSource should request its own source to end and not stop it directly.

Also, if a track is removing itself as an observer to a RealtimeVideoSource, we should
stop the underlying source only if this one does not have any other observer.
Covered by updated test.
