Adding additional test for filtering on inner object json in relation to #880

What is this change?

Test addition where we filter on nested inner object.

ex:

{
    "id": "Endor",
    "name": "Endor",
    "character": {
        "name": "earth char",
        "age": 37445,
        "star": {
            "name": "Endor_star"
        }
    }
}

planets(filter: {character:{star: name: {eq: "Endor_star"}}})

select * from c where c.character.star.name= "Endor_star"
