moinmoin-sh 337b8d279e Ensure MariaDB/MySQL can be purged and handle states being deleted out from under the recorder (#43610)
* MariaDB doesn't purge #42402

This addresses  home-assistant#42402
Relationships within table "states" and between tables "states" and "events " home-assistant#40467 prevent the purge from working correctly. The database increases w/o any purge.
This proposal sets related indices to NULL and permits deleting of rows.
Further explanations can be found here home-assistant#42402
This proposal also allows to purge the tables "events" and "states" in any order.

* Update models.py

Corrected for Black style requirements

* Update homeassistant/components/recorder/models.py
