RCA

When the universal link handling reaches the following code to invoke the deep link, the sections are empty. It appears to be a regression introduced during the Swift rewrite. The sections configuration must be populated in viewDidLoad and not it does it only on viewWillAppear.

The fix is more of a workaround. It's not ideal that universal links depend on sections or rely on BlogDetailsViewController in the first place. The app needs to adopt something more like the Reader navigation system with a root coordinator handling every single possible route.
