Do not show status bar on first bypass attempt

The keyguard status bar has different paddings. Showing it for 0.5
seconds feels janky.
From now on, if we're bypassing, we'll only show it after face auth fails

Test: reach, press power, look at status bar: gone
Test: reboot, reach, press power, look at status bar: visible
Test: reach, press power, wait for auth filure, look at status bar: visible
Test: reach, pull down, wait for auth filure, look at status bar: visible
