    mpris: Emit TrackListReplaced signal when tracklist size changes
    
    Following the previous commit, the MPRIS tracklist is no longer
    static: it is now updated when the player playlist changes.
    This means that its size can also change. In that case, the
    TrackListReplaced signal needs to be emitted to notify that the
    tracklist has been replaced.
    
    closes: #336
