docs are wrong about cloneOpts.remoteCallback

[calebTomlinson]

referring to http://www.nodegit.org/guides/cloning/gh-two-factor/
The docs tell me that I should use the following options object for cloning with oauth.

cloneOptions.remoteCallbacks = {
  certificateCheck: function() { return 1; },
  credentials: function() {
    return NodeGit.Cred.userpassPlaintextNew(GITHUB_TOKEN, "x-oauth-basic");
  }
};

However that doesn't work and isn't what is in the tests.
I ended up using something like

var cloneOptions = {
    fetchOpts: {
      callbacks: {
        certificateCheck: function() { return 1; },
        credentials: function() {
          console.log(token);
          return nodegit.Cred.userpassPlaintextNew(token, 'x-oauth-basic');
        }
      }
    }
  };
