Framework: Ensure Intent.ACTION_USER_PRESENT Is Sent

If the user set a keyguard delay (AOSP-Secure-Delay)
	and the screen turned off, many processes will
	thus assume the user is no longer present (true).
	If the screen is turned on before the keyguard
	enables itself, the USER_PRESENT broadcast is never
	sent and the app/process will not know the user has
	returned to using their device.
