Fix race condition with remote animation cancel/finish

When the animation is canceled, a call to finish is also
sent for clean up purposes. If the user unlocks with an
activity animation and then hits the power button
immediately, make sure the keyguard state gets correctly
set to shown.

Also, add more logging strings about why they WM keyguard
state is being updated.

Also, remove the errant call to show bouncer, which could
pop up in this scenario.
