Fixed navigation bar to show itself after creating a new user through

keyguard ui.

When going through keyguard ui, the provisioned navigation bar is
hidden. When we then create a new user, we switch to using the
unprovisioned navigation bar, so we don't reset the state for the
provisioned navigation bar.
