telephony: SignalStrengh: Don't calculate a LTE snr if the srq is invalid

If the previous values are invalid and signal quality is -1, chances are there's
no LTE signal at all, so don't calculate the SNR and mark it invalid as well.

This fixes the strength indicator in GSM devices where it was being skewed
by the ghost LTE value

Frameworks: Quiet Hours Change Logic (1/2)

12:00am - 12:00am = 24 hours
	(Or any "==" time)

This makes more sense for the user
	if they have the direct ability
	to toggle quiet hours.
	The feature should work as-is
	and in a 24-hour on/off manner
	through using the toggle.
