Added a test around `NO_AUTO_VALUE_ON_ZERO`:
- The mysql `NO_AUTO_VALUE_ON_ZERO` mode should be disabled when inserting fixtures in bulk, this PR adds a test to make sure we don't remove it by mistake - If we live this mode enabled, a statement like this wouldn't work and a `Duplicate entry '0' for key 'PRIMARY'` error will be raised. That's because `DEFAULT` on auto_increment will return 0 ```sql INSERT INTO `aircraft` (`id`, `name`, `wheels_count`) VALUES (DEFAULT, 'first', 2), (DEFAULT, 'second', 3) ```
