Correctly include order id in return auth spec

The route to update a return authorization must include the order number
as id:

    /admin/orders/:order_id/return_authorizations/:id(.:format)

The spec only worked because the controller's ivars were not reset
between requests and the order was already set. But Rails 7 will reset
the ivars and it failed finding the order without a given id.
