* Add org_id to correlations

* Add tests

* Allow org_id to be null in case org_id=0 is used

* Create organization to ensure stable id is generated

* Fix linting

* Ensure backwards compatibility

* Add deprecation information

* Migrate correlations indices

* Default org_id when migrating

* Remove redundant default

* Make PK non-nullable
