MediaPlayer.Playlist.playbackMode does not emit changes (onPlaybackModeChanged) usually until you change track

This would block music-app landing as it creates some weird behaviour.

1) Ensure shuffle is off and restart the app
2) Play a track in an album to create a queue
3) Turn shuffle on
4) Turn shuffle off
5) Wait for EOS
6) Next track is a random track!
7) Wait for EOS
8) Next track is a correct track

The problem was actually happening in media-hub.

The following still occurs on silo009

What happened:
1) Turn shuffle off
2) Restart the app
3) Create a queue
4) Turn shuffle on
5) Press next
6) This is always the next track
7) Press next
8) This is a random track

What was expected:
At step 6) a random track is played

@ahayzen I am not really seeing that, although I must admit that the output of std::random_shuffle(), the function that we use to randomize, is some times not as random as I would like. How many tracks are in your list?
