On a failed restart() the processor set processedTrack to the LiveKit-owned
input track. LiveKit's internalStopProcessor() stops processedTrack and then
republishes _mediaStreamTrack — the same object — so any later
stopProcessor()/teardown killed the live mic for the rest of the session.
Leave processedTrack undefined so LiveKit falls through to its own track.
Unit-tested.
