[Bouncer] Only show swipe up and try again...

when face auth is enrolled and face auth fails.

This was previously submitted and then reverted, but the revert was
prompted by some additional changes I made to the bouncer.

Fixes: 259007288
Test: Enroll in FP and face. Open bouncer and auth via face. Turn off
and on and open bouncer again to view initial message.
Test: Unit Test
