[MIG] contract: Migration to 15.0

Most changes are related to the switch from jinja to qweb in mail templates.

Also included:
- convert deprecated onchange that returns a domain and other deprecation warnings
  (see below)
- Add migration scripts from version 14.0 (force the update of the mail templates)
- Fix warnings from pre-commit checks

Fixes depreciation warnings:

- onchange method ContractAbstractContractLine._onchange_product_id returned
  a domain, this is deprecated
- SavepointCase is deprecated:
  https://github.com/odoo/odoo/blob/15.0/odoo/tests/common.py#L742
- assertDictContainsSubset: According to:
