RecyclerView: accessbility bug for hiddenNonRemove view

When hiddenNonRemove view gets added in prelayout pass
then later animated again after post relayout, the accessbility
flag is messed because onLeftHiddenState() and onEnterHiddenState()
are called in same layout cycle. There is a deferring mechanism
that postpones changing the accessbility flag until layout finishes.
onEnterHiddenState() incorrectly assigned view's current accessbility
to mWasImportantForAccessibilityBeforeHidden. The view's current
accessbility flag hasn't been synced to pending value yet. The
messed mWasImportantForAccessibilityBeforeHidden gets restored
to view in next onLeftHiddenState().

Test: hiddenNoneRemoveViewAccessibility
