    clutter: Update ClutterGestureAction point position before ::prepare
    
    We might want to perform distance/threshold checks in the ::prepare
    vfunc, but we didn't record the last motion event yet. This used to
    give a delta of 0/0 between the press and last motion coordinates,
    despite the ClutterGestureAction having a trigger threshold. This
    happens no longer.
