      1. Start with a Moodle site with several course categories and courses.
      2. Open Site administration => Courses => Manage courses and categories
      3. Find one of the courses, open the dropdown menu, choose Delete
      4. Under "What to do" choose "Delete all - cannot be undone"
      5. Open Site administration => Plugins => Admin tools => Recycle bin
      6. Modify the lifetime for both of the lifetimes to a few seconds
      7. Wait one minute - we need to wait for the lifetime you configured earlier to pass
      8. Open a console and run 

        php admin/tool/task/cli/schedule_task.php --execute="\tool_recyclebin\task\cleanup_category_bin"

      I'm seeing this in my cron output...

      ```
      Scheduled task failed: Cleanup category recycle bin (tool_recyclebin\task\cleanup_category_bin),Can not find data record in database table course_categories.
      Debug info:
      SELECT id,parent FROM

      {course_categories}

      WHERE id = ?
      [array (
      0 => '1255',
      )]
      Backtrace:

        ```

      It seems to be looking for a course category in the recycle bin that doesn't exist in the database.

      While this isn't great, isn't it even worse that the task fails because of this? I would have thought it would be better that it registered this issue and then carried on.
