Sink the floating reference on the visualisation element

        * src/backend/bacon-video-widget-gst-0.10.c (setup_vis):
        Sink the floating reference on the visualisation element
        before giving it to playbin2, so that we can make sure we own
        the ref regardless of what playbin2 does internally. playbin2
        currently sinks the element itself, but may change.
