Before this commit, a 308 on a route with a modelconverter for a model
that have a seo_name field will crash with an exception:
Cannot iterate on RequestUID
Another simplest solution was to use a with_user(SUPERUSER_ID) but in this case
it bypass the security set and display the name of the record even if not yet
published.
How to reproduce:
Create a 308 from /shop/<product> to /mag/<product>
Unpublish product 10
Try to access /shop/product-10
You have an unmanaged '500 internal error"
because slug_matching -> build -> to_url -> slug with a record with Requestuid
as env._uid.
