screen-cast-stream: Also release mapping id when clearing stream

Browse Source 
Use the previously added API to release acquired mapping ids, when the
corresponding stream is destroyed.
Otherwise, the remote desktop session would maintain a whole bunch of
unused mapping ids, as their corresponding streams are already
destroyed, but maybe not the session.
Such situation would be a remote multimonitor session, where the amount
of used virtual monitors changes multiple times during the session.
