Fix bug preventing pattern bouncer entering half height mode.

I messed up the resource qualifier for the guideline (referred to the
PIN pad one after a copy+paste), so the top guideline for the pattern
view was never updated, preventing it from only using half of the screen
in HALF_FOLDED mode.

Bug: 199991560
Test: Manually verified.
