@Vinai are you able to review this change?

@RokPopov at this stage we're not sure if this is the only case, but we've definitely seen failure notifications turn up after successful ones before, which has been confusing, as...

@LexKoomen if you are using `replace` in `composer.json` to remove all graphql modules, then adding it as a requirement in this module won't affect anything.

Failing tests do not appear to be related to this change, but a missing Symfony class: ``` Error: Class "Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator" not found ```

I would suggest moving all table information to `db_schema.xml`, and removing setup scripts.
