When trying to reference a smart proxy by name in the API and the name contains a full stop/period/"." then Foreman can't find the proxy resource.

Note in this example it's stripping off the ".fm" suffix:

GET http://0.0.0.0:3000/api/smart_proxies/foreman.fm => "Resource smart_proxy not found by id 'foreman'"

Started GET "/api/smart_proxies/foreman.fm" for 127.0.0.1 at 2013-10-25 15:24:03 +0100
