Can launch into the lock screen with setup wizard style

The trampoline currently always uses the settings style for set action
new password. When called during setup wizard, it should launch the
setup wizard style.

Test: Added robotests for launching activity and copying setup wizard
extras. Also manually tested with an application when device is
provisioned and not provisioned.
