Make sure keyguard unlock resets pip corners

Make sure that after the ag/24811629 workaround
was introduced, we update the finishTransaction
and startTransaction to reflect correct corner radii of a PiP task.

This makes sure that when these transactions are applied via
KeyguardTransitionHandler, PiP doesn't end up in a state with zero corner
radius.
