$auth.getAuth() returns null for anonymous user?

Version info

Other (e.g. Node, browser, operating system) (if applicable): Win 10 Firefox 49.0.2

Test case

Don’t have time at the moment

Steps to reproduce

1. auth anymously.
2. use following directive in resolve of route you want to disallow logged in user to view. i found here that $auth.getAuth() returns null $auth = firebaseAuth from factory:

	$stateProvider
	//game -> login
	.state('login',{
		url:'/login',
		controller: 'GameLoginCtrl',
		templateUrl:'views/desktop/game/login.html',
		resolve: {
			loadMyFiles:function($ocLazyLoad) {
				return $ocLazyLoad.load({
					name:'app',
					files:[
						'js/controllers/GameLogin.js',
						'css/login.css'
					]
				});
			},
			'currentAuth': ['$q','$auth',function($q,$auth){
				var u = $auth.$getAuth();
				var p = $q.defer();
				
				console.log(u); // null, but localStorage shows anonymous user.
				
				if (u) {
					return p.reject('ALREADY_AUTH');
				} else {
					return p.resolve();
				}
			}]
		}
	})

Expected behavior

Actual behavior

Yup, you can do that. $waitForSignIn() is fulfilled with the auth state, so you can do:

resolve: {
  "currentAuth": ["Auth", function(Auth) {
    return Auth.$waitForSignIn()
      .then(function(currentUser) {
        if (currentUser !== null) {
          throw new Error("User logged in");
        }
      });
  }]
}

looks like a race condition. if i wait a while and navigate to the url without a page refresh, it shows up correctly
