Fix Certificate authority installed notification is gone when turning off and on the work mode.

cause: Work mode is turned on before entering USER_STOPPED state.
Thus, BOOT_COMPLETED broadcast is not sent, but the notification has been dismissed.

use USER_STARTED + USER_UNLOCKED because both are foreground.
