`Balanced.Auth.get('isGuest')` gets set when the Auth.User gets created. A visitor can end-up in some views with no Auth.User created (visiting pages directly). The Auth.User code is very stateful so I'd rather have this model manage its own `isGuest` method. 

When I'm not logged in and I visit the `#/marketpalces/apply` route directly the isGuest doesn't get set. Maybe `isGuest` is not the right name for this method. I'll update it.
