Bugfix: Don't show items without links in Recently viewed

This is a quick patch for https://www.pivotaltracker.com/story/show/60888148

The problem is that going to My Work adds the current user to the recently viewed list (is this even intended?),  but without the viewLink property. When viewing a user (by going to `/people/id`) this works fine. I've traced this down to `GGRC.page_object` not having the url set, but I couldn't figure out why this is happening. 

I'd appreciate a hint how `GGRC.page_object` is being inferred in the first place.
