Let the finishing transition commit the visibility

There may have visibility changes by WindowContainerTransaction
before calling Transition#finishTransition.

To make sure the visibility of transition participants can be
committed in Transition#finishTransition, if there is a request
to change activity visibility in a finishing transition, then
only set the requested visibility without commit.
