Compatibility fix: Updates made on the scene must be processed with a queued connection

This connection was queued in the views before, but we don't do that
anymore, instead we re-use the _q_emitUpdated slot and process
pending updates on the views there.

Makes tst_QGraphicsView::viewportUpdateMode happy again.
