Update UnlockMethodCache when keyguard visibility changes

When screensaver (not AOD) starts, the device is still "screen-on".
Keyguard can come up in the background, and if the user dismisses
screensaver, the cache will not have been updated but the device now
requires authentication

Fixes: 65487788

Test: 1) go to settings, start screensaver
2) wait 5s for keyguard to come up beneath
3) tap on screen to dismiss screensaver
4) lock or fingerprint icon should be shown, instead of unlocked icon
