""" Update event configuration from its event type. Depends are set only
on event_type_id itself, not its sub fields. Purpose is to emulate an
onchange: if event type is changed, update event configuration. Changing
event type content itself should not trigger this method.
When synchronizing tickets:
* lines that have no registrations linked are remove;
* type lines are added;
Note that updating event_ticket_ids triggers _compute_start_sale_date
(start_sale_datetime computation) so ensure result to avoid cache miss.
