Currently, the migration key is stored through a workaround as a config parameter,
because the behaviour needed to be changed in stable.
Now, several things can be fixed:
- `account_peppol_migration_key` is now a field on `res.company`, not `account_edi_proxy_client.user`
- `account_peppol_attachment_ids` can be removed as the specs changed and it's no longer necessary
- `peppol_proxy_state` can be removed as it's no longer useful after `enable_peppol` was added
- SQL constraints need to be changed to only include active users.
This allows users to deregister/migrate away from Peppol and then re-register later, with their previous edi user being archived
