Fixed device info reporting for media player

Fixed issue relating to audio device information reporting to audio
playback configuration. The self routing listener is registered during
play start and temporarily remove during stop. Also fixed issue where
removing the last audio routing change listener would stop the media
player from further reporting device changes to audio playback
configuration monitor.
