Before this commit, every model having website_id would have the default
`set null` as ondelete value for that field. Exception for `ir.ui.view` and
`website.redirect` which are set to `cascade`.
This meant that deleting a website would basically transform all its specific
records into generic ones.
That would lead to unwanted behavior, such as multiple `ir.attachment` with
same URL, when 2 websites had been theme-customized. Deleting one of the
website would result in later crashes when trying to open theme customization
in the remaining website(s), since those website would find their specific scss
custom attachment as well as the generic one from the deleted website.
Probably more behavior might be problematic when deleting a website before this
commit.
To summarize the choice of this commit implementation, every model not existing
outside website module are set to `cascade` (website.redirect, website.menu,
product.wishlist..).
The rest should be in restrict, as we don't want to delete a whole forum, blog
or job, which should probably be managed case by case to decide what to do.
Thus, restrict is a good choice to notify user of what should be handled.
Some exception remains, ir.ui.view should be delete on cascade while sale.order
should be set to null.
