* Add migration to create missing tabs
In v13, if a tab had groups in both a composition and the content type, the tab might not exist on the content type itself.
Newer versions require such tabs to also exist directly on the content type. This migration ensures those tabs are created.
Also fixes an issue in LeftJoin where nested sql arguments were being discarded.
* Small fixes
* WIP: Integration test.
* Added asserts to show the current issue with the integration test.
* Adjusted the integration test
* Added logging of result. Minor re-order and extraction refactoring in integration test.
