    medialibrary: Wait for all TrackObject-s to be in Tracks before seeking
    
    We currently need to work around the fact that TrackObject-s are created
    async and first added to the TimelineObject-s before the tracks. So we
    need to wait the TrackObject to be in the tracks before the timeline duration
    is updated, and the composition actually contains the gnlobject for the clips we
    are adding to the timeline.
