All of the PlaysOutAudioAndVideoInSync* tests were reporting metrics under
the same name ("sync_convergence_time/synchronization") so that only one of
the tests (whichever ran last) had its metrics reported to the dashboard,
while the others were silently ignored.
I added a suffix to differentiate between them.
