auth: remove redundant AuthUser constructor arguments AuthUser looks up the user based on the first of `user_id`, `api_key` and `username` that is not None *and* does not refer to the default (anonymous) user. In practice, the arguments always refer to the same user, so there's no point in specifying more than one of them.
