Launch to fullscreen when re-open from lockscreen and in PiP

This is a regression from ag/11249465, when SysUI receives
TaskStackChangeListener#onActivityRestartAttempt, it should animate the
task in PiP to fullscreen despite the visibility (invisible in this
case since it's behind the keyguard) it was.
