Changed result of entering credentials after forgot pattern

After pressing forgot pattern and entering credentials, it used to
bring you to the screen to choose a new pattern.  Now you are brought
to the screen to choose any unlock method.  The reason for this change
is that both Pattern and FaceLock are valid possibilities when a
pattern is forgotten since FaceLock can use a pattern as a backup
method.
