[chore] migration to update statuses.thread_id to be notnull (#4160)

# Description

This is quite a complex database migration that updates the `statuses.thread_id` column to be notnull, in order that statuses always be threaded, which will be useful in various pieces of upcoming work. This is unfortunately a migration that acts over the entire statuses table, and is quite complex in order to ensure that all existing statuses get correctly threaded together, and where possible fix any issues of statuses in the same thread having incorrect thread_ids.

TODO:
- ~~update testrig models to all be threaded~~
- ~~update code to ensure thread_id is always set~~
- ~~run on **a copy** of an sqlite production database~~
- ~~run on **a copy** of a postgres production database~~
