[FIX] website: add test for website filter in list view

With the Milk redesign in [1], the possibility to select a website on
the filter/search view on our custom list views (e.g. on website.pages)
to filter out the ones not related to a website and only keep the ones
with a website_id or no website_id (and not shadowed by a website_id
one) disappeared.

It has been fixed in [2], but in order to prevent future breaks, this
commit tests this functionality.
