Unable to restore audio player from notification bar

Description

The resolution to defect #616 (closed) in merge request !1742 (merged) introduced additional logic for the videoBackground flag. When this flag is true, PlaybackService.sessionPendingIntent returns a PendingIntent which does not restore the audio player.

Steps to reproduce

1. Start audio playback and use app normally
2. At some point the song changes and returns the wrong type of pendingintent
3. Attempt to load VLC by pressing the media notification
4. Audio player screen is not restored
