Fix LocationOnScreenTests failure

The issue instroduced by CL [1], mis-understood
isSelfAnimating meaning that will also check if the transition is wait
for animating, but it will break the test that use no_animation theme,
that caused delayed will set as true in commitVisibity then
didn't callback onAppTransitionFinishedLocked -> onEnterAnimationComplete
for activity.

Revert to use isRealAnimating to check if need delay to unblock the test
fail.
