Testing

1. Install Moodle 4.5 or below (a version which can be upgraded to 4.6 or 5.0)
2. Install a new question type we can use for testing. I chose to use (https://github.com/dualcube/moodle-qtype_ddmatch) but any other question type will do.
3. Create a course
4. Create a question bank on the course if one doesn't exist already
5. Add a question of the newly installed type to the bank
6. In any text editor on the new question form that lets you attach a file/image - add one (Should be question text or feedback)
7. Remove the "ddmatch" question type by deleting the question/type/ddmatch directory (or whichever one you chose to install)
8. Upgrade your codebase to previous weekly release of main 
9. After the upgrade has completed, there should be an adhoc task in the table `mdl_task_adhoc` of classname `\mod_qbank\task\transfer_question_categories`
10. Run this adhoc task, either manually by using the `php admin/cli/adhoc_task.php` script or by running the cron again.
11. You should see it fails to execute due to the unknown question type
12. Checkout to the latest main branch.
13. Run the adhoc task again
14. It should now succeed
15. You should then be able to find the invalid questions have been moved to the new question bank on the course, most likely called "A shared question bank"
16. Reinstall the missing question type
17. Edit the question, which should now be editable again that the type is there
18. Confirm that attached files/images are still in place (question text and feedback fields should always still be there. Custom text editors on the question type which don't exist on the base question type, may not be transferred.)

Code verified against automated checks.
