    playbin: make sure elements are in null before disposing

    If a pipeline fails to preroll, it might happen that the sinks are
    put into READY state from playbin's sink activation, but they are never
    set to playsink, so they aren't being managed by a GstBin and will keep
    their READY state until they are unreffed, leading to a warning.

    Prevent this by always forcing them to NULL when deactivating a group

Just noticed I forgot to fix the commit message when fixed the code, it only
forces it to null when not inside playsink.
