Reset NotificationPanelView when pressing power button before fold to AOD animation

When we hit power button during folding: before
fold to AOD transition starts but after we prepared
the starting params of NotificationPanelView it remained
in this state (alpha = 0, translation = -x). So it led
to an issue that user don't see the keyguard.

Added logic that resets this view to its original
state when we are waking up and the animation hasn't
started yet.
