    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 reseting the auth prompt before
    using it in showPrompt.
