[FIX] website_event: restore country events option

With odoo@ac8b0fc,
the 'country_events' class was renamed to 'oe_country_events'. This was
done correctly for JS animations and snippets but not for the 'Country
Events' option in the customize menu. This made the option useless.

This commit solves the problem by supporting the two classes (as it
is a stable fix).
