On the restore side, there's a bunch of one-time setup, device provisioning, etc that we're very much not prepared to do in lieu of running setup wizard, at least at this time. On the backup side, it simply doesn't make sense to back up stuff before the device has been set up. Part of bug 5290261 Change-Id: If1c65e88e2da589d6204232d2b59c3e994f4ed3f
