A paired car that doesn't know the phone's address gets it asked for on the phone

The Bolt in #18 stayed connected only once Gearslip passed it the phone's Bluetooth address,
which was hidden in Settings. After a paired car connects without it, Home asks once per car
and opens About phone. Coming back, Gearslip offers the address it finds on the clipboard. The
car screen says once to finish a step on the phone when parked.
