Changed result of entering credentials after forgot pattern

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.
