  REGRESSION(299875@main?) [iOS macOS] ASSERTION FAILED: it != 
m_trackIdentifiers.end()

Reviewed by Eric Carlson.

Calling AudioVideoRendererAVFObjC::addTrack could trigger a call to 
notifyRequiresFlushToResume,
before returning: as such the track identifier wouldn't have been inserted in 
the hash map yet
causing the assertion.

We ensure that the callback `notifyRequiresFlushToResume` isn't called when
we just added the video track, as no video data would have been enqueued yet: 
so there's
nothing to flush yet.

Re-enabling tests.
