Before this commit, this flow was broken:
- Install website
- Create a new website of your own (not using the one created
automatically from XML data)
- Choose another color palette for that website
- Uninstall the website app
- Reinstall the website app
- Try to choose another color palette for any website
=> It does not work
Indeed, after the uninstallation, the DB is left in an invalid state:
the SCSS customizations attachments of the website that was created by
the user are not removed, they just have their website_id field emptied.
Some code made at [1] was already there to remove those attachments. The
problem is that it only worked for websites which were created by XML
data (at website installation), not by the user. Indeed, the `unlink`
method is not called during uninstallation to remove records that were
created by the user, thus the `unlink` override was not called either.
See [2] for some details.
This fixes the issues by moving this attachment cleaning code in a
dedicated method, called in `unlink` but also in the `uninstall_hook` of
the website app.
This also takes the opportunity to refactor the code involved, in
particular to not even consider customized attachments which do not have
a website_id.
