fix(Transition): should queue update when leave finishes

[edison1105]

Fix #4933

There are two reasons for this

• First, instance.update doesn't run because it's already in the queue.
• Secondly, update() needs to be executed after the emptyPlaceholder is mounted, otherwise it will not find the mount container.
