Subject: [PATCH] fix(FEC-12527): turning on hls debug mode in config causes
 the player to crash (#176)

In some cases hls.js triggers our event handlers (specifically _onAudioTrackSwitched) before the _onManifestLoaded handler. When _onAudioTracksSwitched calls _playerTracks.find, which is undefined, it crashes.
The solution is to initialize _playerTracks with an empty array before _onManifestLoaded fills it with the real values.
