Description of problem: On table recipe_task_bugzilla coulmn recipe_task_id is nullable which can lead to orphans. This should be nullable=False. As part of the migration script deletion of orphans should be done as there could be due to the nature of the constraint.
The recipe_task_bugzilla table has never actually been used, we should just drop it.

There is no expected change in behaviour here, so verification should just be that the database migration succeeds (it did) and that nothing else breaks.
Beaker 25.0 has been released. Release notes are available upstream: https://beaker-project.org/docs/whats-new/release-25.html
