Title: Make it possible to pass extra parameters to prepare_refresh_body

The current code allows extra parameters to be passed to authorization requests. This is useful if I want to for example add `client_id`/`client_secret` to the request. I needed the same functionality for token refresh requests, so I changed `prepare_refresh_body` to pass unknown keyword arguments directly to `prepare_token_request`.
