Restart the iPhone over USB. Afterwards a person must type the passcode once
Ask the user first. After a restart iOS ignores the Bluetooth keyboard until a person
unlocks the iPhone by hand once, so unlock cannot do it. The USB screen and lease
come back by themselves in about a minute.

Parameters
lease *string
Lease id exactly as acquire printed it, e.g. "studio:42"

Mac slug from list, e.g. "studio". Needed when several Macs are online
