Title: Return 404 for unknown Location/Clients.

It assumed you'd never ask for a unknown URN, and the page exploded with
a 500. I need the usual response codes for the client gem.

This will resolve at least one exception in Honeybadger, so I'll probably go trolling through there and the associated tracker tickets when I deploy.
