REST API: Ensure "Allow" header is returned for OPTIONS requests. 

This changeset ensures `$request->set_url_params()` is called while fulfilling OPTIONS requests, where previously it was skipped because OPTIONS requests short-circuit the logic in `dispatch` which handles this setup for other request methods. Omitting the URL parameters prevented the Allow header from being set.

Props killua99, noisysocks.
Fixes #45753.
