upgrade-calendar-quick-add (U1704)

A calendar view uses quick_add, renamed quick_create in Odoo 17.0.

Applies to Odoo 17.0 and later.

What it does

Reports quick_add on <calendar> views.

Why is this bad?

Odoo 17.0 renamed it quick_create: the view fails to validate.

Fix safety

Safe: the attribute is renamed.
