Fix NPE when restoring setup activity

If the setup activity ever needs to restore itself after being killed, we were
restoring the Activity object's state (i.e. rebuilding the UI) before we
restored the state of our class. Since the Activity necessarily depends upon
our object's state, Bad Things can [and will] happen.

The solution is simple -- save our object's state last, but, restore our state
first.
