Fix for django 1.5 and tastypie 0.9.14

Django 1.5 now requires that there be quotes around namespaced url tags like this one. I don't have an install of django pre 1.5 to test in to make sure that this doesn't break backwards compatibility. 

Also, tastypie 0.9.14 is putting the view into the context to be rendered and we're crashing on the view being unrenderable to json.
