I've recently upgraded from v1.3.3 to v2.0.0-alpha.10 and I'm facing some issues that didn't exist before, so I've setup a test instance on Heroku to isolate them. I can share the instance if needed, but it's easily reproducible.

I created a list_item table with a field product_id referencing product (id, name), with the proper foreign keys and relationships. On the permissions tab for list_item I have limited the number of rows to 0 and enabled the custom check {"product_id":{"_is_null":true}}. I've populated it with some test data.

However, this query:

{
  list_item {
    list
  }
  product(where: {list_items: {list: {_eq: "OWN"}}}) {
    id
    name
    list_items {
      list
    }
  }
}

Gives this result:

{
  "data": {
    "list_item": [],
    "product": [
      {
        "id": 1,
        "name": "Product 1",
        "list_items": []
      },
      {
        "id": 2,
        "name": "Product 2",
        "list_items": []
      }
    ]
  }
}

The list_item query returned empty, as it should, so did the list_items array relationship on the product. However, the product query shouldn't return any row as there's no row allowed for this role that matches the where condition.
