If the user has limited_access, download_security field was not read due to the
override of check_field_access_rights and so the field not set.
When you try to access/read it, you got: Selection is not iterable.
Now we check in sudo the download_security.
We also add the **kw that should be present in all routes.
Avoid: "slide_download() got an unexpected keyword argument 'debug'"
We also remove this controller from the sitemap.
