Closing game webcame in Jitsi

When stepping in Jitsi, the game webcam (from mediaManager) was not shut down.
And when enabling/disabling the webcam in Jitsi, the webcam in mediaManager was also
enabled/disabled. This PR fixes those issues.

It also fixes a race condition when closing a Jitsi where the mic/cam would be enabled at the same time.
