[FIX] orm write: do not try to store computed & stored fields for relational records deleted by *2many fields

opw-613772

Due to additional security rules, the transactions made as public user will have a new partner_id. The transaction needs to be retrieved as admin to be set in the context.
The operations in payment_get_status are made as superuser but the session_id is checked in the assert above to avoid url manipulation.

The group public is defined in base so no need to add security rule in website_payment module (same as for portal)

See #1982

During the update of a module, the existing foreign keys are dropped if they have a different ondelete_rule than the one specified on the field.
The foreign keys for many2one transiant -> non-transiant are created with cascade rule by default (see `m2o_add_foreign_key_checked` method) so the check needs to be realised in the same conditions.

The tax_amount field should contain the basic amount (without tax) for base tax code. (opw 613470)

When sending an email, both formats 'Name <email>' or '"Name" <email>' can be used for fields 'From', 'To' and others. If the name contains unicode characters, a regex only matching '"Name" <email>' was used to encode the name with RFC2047. That meant that the name was not encoded and eventually dropped, using only the email part.
Instead of using a limited regex, use the parseaddr method from email library.

When a tax included has a several childs, the source line should not be duplicated for each tax.
