Update multi biometric flow for SUW

Currently, if a user has completed a fingerprint/face enrollment
in SUW and they press the back button, we show the UI for each, and
it fails with no error.

This change makes it so that if a user completes 1 fingerprint or 1
face enrollment, it will no longer try and enroll them again if they
have failed.
