Handle non-started LayoutTransition animations correctly

A recent change to LayoutTransition noop'd animations in non-visible
parents, to avoid artifacts like scaling/moving from (0,0,0,0). But there
was logic in ViewGroup that didn't account for transitions that didn't actually
run an animation, causing a disconnect between the state of a parent (getting ready
to remove an item later) and the state of the transition (not running, therefore
not needing the child to be removed later).

The fix was to detect when the transition did not start and avoid adding the
view to the list of children to be removed later.
