[FIX] website_event, website_sale: _order on is_published

As fbbf24f introduced multiwebsite and `website_published` became a
related and/or a computed field (depending of the mixin), we should not order
on this field as it is not on DB anymore.

We now have the field `is_published` that replace `website_published`.
