fix for #158

@settinghead please review. This is just the fix for exception. The main fix for this issue is in the Core API.
@settinghead Aha, I see. The user is populated in here https://github.com/Rise-Vision/common-header/blob/master/src/js/controllers/ctr-user-settings-modal.js#L111
We don't really need to $scope.$watch here. $scope.user.status could be updated right after getUserProfile results are received. I'm okay with keeping it either way.
