Parent and child filters with mutually exclusive conditions on the same child docs don't produce any results

[islamaliev]

If a parent filter on secondary doc (e.g. Author) has a condition on a child primary docs (e.g. on Book: published.rating) and selected fields have the same child docs (published) with it's own filter that excludes conditions from the first filter, the result will be empty.

Make this test work:

var bookAuthorGQLSchema = (`
	type Book {
		name: String
		rating: Float
		author: Author
	}

	type Author {
		name: String
		age: Int
		verified: Boolean
		published: [Book]
	}
`)

func TestQuery_ParentAndChildFiltersHavingMutuallyExclusiveConditions_ShouldDistinguishFilters(t *testing.T) {
	test := testUtils.TestCase{
		Actions: []any{
			testUtils.SchemaUpdate{
				Schema: bookAuthorGQLSchema,
			},
			testUtils.CreateDoc{
				CollectionID: 1,
				DocMap: map[string]any{
					"name":     "John Grisham",
					"age":      65,
					"verified": true,
				},
			},
			testUtils.CreateDoc{
				CollectionID: 1,
				DocMap: map[string]any{
					"name":     "Cornelia Funke",
					"age":      62,
					"verified": false,
				},
			},
			testUtils.CreateDoc{
				CollectionID: 0,
				DocMap: map[string]any{
					"name":      "Painted House",
					"rating":    4.9,
					"author_id": testUtils.NewDocIndex(1, 0),
				},
			},
			testUtils.CreateDoc{
				CollectionID: 0,
				DocMap: map[string]any{
					"name":      "A Time for Mercy",
					"rating":    4.5,
					"author_id": testUtils.NewDocIndex(1, 0),
				},
			},
			testUtils.CreateDoc{
				CollectionID: 0,
				DocMap: map[string]any{
					"name":      "Theif Lord",
					"rating":    4.8,
					"author_id": testUtils.NewDocIndex(1, 1),
				},
			},
			testUtils.Request{
				Request: `query {
					Author(filter: {published: {rating: {_gt: 4.8}}}) {
						name
						published(filter: {rating: {_lt: 4.6}}) {
							name
						}
					}
				}`,
				Results: map[string]any{
					"Author": []map[string]any{
						{
							"name": "John Grisham",
							"published": []map[string]any{
								{"name": "A Time for Mercy"},
							},
						},
					},
				},
			},
		},
	}

	testUtils.ExecuteTestCase(t, test)
}

This happens because the top select filter does the final filter pass with the top (parent) filter on the parent doc with the children filtered by the child filter.
