Test: manually
  1. Enroll fingerprint and unlocking using fingerprint should dismiss lockscreen
  2. Enroll face auth with bypass enabled, lockscreen should be dismissed on success
  3. Enroll face auth without bypass enabled, lockscreen should not be dismissed on success
  4. Enroll trust agent, keep device unlocked using trust agent, lockscreen should not be dismissed
  5. Enter pin/pattern/password, lockscreen should get dismissed.
  6. Set auth method to swipe, lockscreen should be visible and swiping up should dismiss it.
  7. Set auth method to none, lockscreen should not be seen when waking up from sleep
