Adding namespacing spoofing to harbinger

This is a shot in the dark for a possible solution to a potential
production development problem. Namely that the Rails router is unable

It is possible that Kaminari is the culprit, as there is a long

Because Kaminari, Rails router, namespacing, and url_for means we
can't have nice things.
