Correctly stub a basic-auth request
Correctly stub a basic-auth request

faraday does not put username:password in the request url for a
basic-auth request. Instead, it base64 encodes them and puts it in the
Authorization header, according to
https://en.wikipedia.org/wiki/Basic_access_authentication#Client_side
So we need to stub the GET request to a url that does not include
username:password.
