commit 27a2fdfb8ad1606bdb686c35e30ae894dd037588 changed the insert reverb behavior when it is attached to a track in that the reverb tail is silenced immediately when the track is paused. The tests have been modified to test the insert reverb on session 0. Change-Id: I90c6fec40167966853acfeaa4dec2b96f9e7839f
