Gets matching responses to the URL and request method from the fixture. First, checks
if a matching response is in the <code>mUrlToResponse</code> map. If that's not the
case, it goes on to check the regular expressions for a match.
@param {string} sMethod The request method
@param {string} sUrl The URL of the request
@returns {object} An object with the properties <code>responses</code> and
  <code>match</code>
