Subject: [PATCH 2/2] unlockDialog: Properly reset auth prompt when showing it

If a user hits escape twice really fast when coming back to
their machine to unlock it, they made end up getting presented
with a non-functional unlock screen that doesn't show their
user icon and doesn't ask for a password.

This is because showPrompt assumes that if an auth prompt already
exists, it's ready to go. That may not be true, if it's in the
process of getting torn down at the time because it's in the middle
of a cancel animation.

This commit solves the problem by ensuring the auth prompt is always
in a fresh reset state before showing it.
