Joe Bolinger 43d978bd7b Fix back navigation in biometric enrollment.
Using the back buttons can cause a crash in at least two cases. Skipping
face enrollment and then starting/stopping any enrollment can lead to
an invalid token and failed HAT request. Backing out of the activity and
restarting it can also lead to using a stale token that fails.
