Nested arguments are not passed down to child elements

I have following example:

```
{
  company(id: "123") {
    name, 
    directors(active: true) {
        name
    }
}
```

so problem is once we call the nested `directors` in the resolver we pass just the `[value]` which is the company data but the arguments are skipped. This is a valid GraphQL query though.
