Fixed an issue where using UDFPS always dismissed the shade

Because we were only checking for the bouncer to be shown and not
the alternative auth interceptor, the unlock mode always ended up
being unlock_collapse instead of dismiss_bouncer.
The isBouncerShowing() was already taking into account the alternative
auth path, but the bouncerIsOrWillBeShowing() didn't
