[FIX] website_sale_slides: force sudo addition of course members at SO confirmation

When a sale.order containing a slide.channel registration product is confirmed
by a person that does not have rights on slide.channel (typically a salesman),
the system will throw an error.

This commit forces the addition of members by using a sudo on the
"_action_add_members" method.

We assume that when confirming a sale.order, we want to add the members and
enable their access to the course even if the person confirming the sale.order
does not have e-learning privileges.
