[IMP] event_sale: remove is_paid and store payment_status

We remove the is_paid field and based the logic on the payment_status
as these two fields are a bit redundant. It is also in preparation
to the removal of the field auto_confirm on the event.event model.
The goal is to ease and simplify the management of registrations.
