This fix ensures Odoo still includes its built-in apps when no custom add-ons location is configured. It helps prevent startup or missing-app issues for deployments using the default setup.

This update improves how Odoo cleans up pending setup actions when an app or module is uninstalled. It helps prevent uninstall errors by removing related follow-up tasks before the underlying actions are deleted, making maintenance more reliable for administrators.

In order to module uninstall work properly
--> unlink ir.action.todo which are related to actions which will be deleted. on-delete cascade will not work on ir.actions.actions so we will need to do it manually
--> improve need_action_data method also to avoid error.
