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.
