Remove duplicate call to update PIP bounds on PIP expand

Remove the callback to update bounds in
resizeAndAnimatePipUnchecked because:
1. animateResizePip already attaches a callback to update the
bounds state in onAnimationEnd
2. it updates the bounds too early before finishResize() is
called, which causes finishResize() to not know the pre-resize
bounds needed to perform the crossfade animation

Bug: 188829986
Test: enter PIP with seamless resize turned on, double-tap to
expand and unexpand, crossfade animation looks right
