When an expect fails (resulting in an error), the response is lost.

Suppose we expect a 200, but actually get a 422 (or some other error code), with info about the error in the response.

return request(app)
  .get("/user")
  .expect(200)
  .then(function (res) {
    // Do stuff ...
  })
  .catch(function (err) {
    // PROBLEM. Don't have response from server.
  });

If we go into the catch, there's no way to print the server's response.
