fix(sync): show Sync brand name when signin up/in for Sync

Fixes #1339.

WIP, we might need string changes.
What if we modified BaseView.prototype.beforeRender to return a promise so that you could just do:

```js
   return FormView.protytpe.beforeRender.call(self)
        .then(function () {
           if (self.hasService() && Session.isSync()) {
             return self.setServiceInfo();
           }
         });
