Allows `access_(git|api)` to anonymous users

The `access_git` and `access_api` were currently never checked for
anonymous users. And they would also be allowed access:

  An anonymous user can clone and pull from a public repo

  An anonymous user can request public information from the API

So the policy didn't actually reflect what we were enforcing.
