SUW: Update wizard scripts for Pie

The google suw flow has changed a little bit and added some new flow
choices in Pie, so our scripts need to be updated to match it. This
fixes the restore choice screen being shown twice.

Also reorganized the order of the wizard action results to move the
resultcode from the beginning to the end. This is a noop change that's
just to bring it inline with google's suw scripts.
