fix: revoke access token on duplicate auth code user

* feat: add x-tinyauth-location to nginx response

Solves #773. Normally you let Nginx handle the login URL creation but with this "hack"
we can set an arbitary header with where Tinyauth wants the user to go to. Later the
Nginx error page can get this header and redirect accordingly.

* tests: fix assert.Equal order
