mod_http_oauth2: Fix inclusion of role in refreshed access tokens `refresh_token_info` does not carry the role, and due to behavior prior to prosody trunk rev a1ba503610ed it would have reverted to the users' default role. After that it instead issues a token without role which is thus not usable with e.g. mod_rest
