This resolves RTW-112. Specifically, it uses Postgres' NULLS NOT DISTINCT. Note that this feature has just been added to SQLAlchemy (more information can be found in the original issue, pr and release notes). But since it's just been added, alembic doesn't have a command or option for it. Therefore I wrote a plain SQL command as migration.
Also had to remove
create_artefact_builds
helper as it could occasionally break uniqueness constraint. So tests can fail randomly.
