    dnd: Stop using getTweenCount()
    
    Those checks were carried over from the very first DND implementation;
    if they were ever actually required at all, this is no longer the case
    as we moved away from Tweener for all our animations.
    
    The number of cases where an extension is still using Tweener, creates
    draggable actors, *AND* requires the checks for proper functioning
    should be indistinguishable from zero, so drop the code.
