Skip window transform if SwipePipToHomeAnimator's running
Launcher tries to set the window transform on the recents animation
leash when it's settled on end target, which might conflict with
SwipePipToHomeAnimator and causes flash/flick at the end of the
transition. Simply skip the window transform since
SwipePipToHomeAnimator is the one solely responsible for updating the
leash in this case.
