Title: Make nock throw error if there isn't an interceptor for a nock'ed url

As per this documentation: https://github.com/pgte/nock#read-this
Nock should throw an error if you don't have a matching interceptor for a url, but previously have HAD a matching interceptor.
This PR restores that behavior and fixes https://github.com/pgte/nock/issues/228
