The player state of PlayerBase was not kept in sync with its
corresponding AudioPlaybackConfiguration. This caused
the configuration to never be removed and gc'd because
the state of PlayerBase when released was always the
unitialized state of 0 == released state.
Test: use a MediaPlayer then call release, verify the player
is not showing in the AudioService dumpsys
