fix nav for editing and viewing completed registrations
 - don't mess with the rootScope anymore
 - if the path has no pageId and the registration is completed, go to the reviewRegistration page
remove fields for completed registrations on register page
 - all handled on reviewRegistration now
 - note: if on reviewRegistration and user clicks title, there is a brief flicker as the page goes to the register start page and then redirects back to review page
