[IMP] event: clean code about synchronizing partner / sale order line

PURPOSE

This commit is part of ticket model support directly in event application.

SPECIFICATIONS

In this commit we make a quixotic attempt to clean call chain implied by
making registrations online, either in event frontend (website_event) or
with eCommerce inclusion (website_event_sale). Purpose is to get rid of some
preparation and data management methods to handle most of the code directly
at CRUD level whenever it makes sense.

We notably

  * move at create and write level support of partner_id update: updating
    its name / email / phone / mobile;
  * move at create and write level support of sale_order-id update: updating
    event, ticket, partner;

Using that and some code cleaning some methods are removed and call chain
is a bit reduced.
