    Avoid crash using Previous/Next (multimedia keys)
    
    Only call _get{Previous,Next}Track if there is a previous/next track.
    We didn't need to check it before because the Previous/Next buttons are
    disabled in the first/last playlist's track. Now, with the Multimedia
    keys we need to force the same behavior.
