Support Odoo 18

[petrus-v]

Just open this issue as self remember from fist try

• In odoo 18 there is a change (odoo/odoo@ccf3c1e) that expect unit test launcher

                if not result.wasSuccessful() and BaseCase._tests_run_count != 1:
                    _logger.runbot('Disabling auto-retry after a failed test')
                    BaseCase._tests_run_count = 1

wasSuccessful does not exists while launching test using pytest. commenting those lines seems to works as an ungly workaround.

• Also we get an logging error because configuration seems to be changed a bit late which was introduce by this commit odoo/odoo@1f3a15a#diff-80aef099e5fb41cc09e699d35b749152aca50caf5b0bc16c400081c29023fbecR95

• Also a warning is shown while open registry:
  ``
  `/.venv/lib/python3.12/site-packages/pytest_odoo.py:167: DeprecationWarning: Use directly odoo.modules.registry.Registry
  odoo.registry(db_name)

I (we) needs to spend more time to investigate a bit more and properly fix that some how

  • Support pytest-odoo OCA/OCB#1262

• for the 2 other parts Support odoo>=18.0 #80 avoid logging error/warning
