`burned` field is not respected 

```js
const client = getClient('ahp');
const query = client.itemListByCollectionId('244', { burned: false, orderBy: 'blockNumber_ASC', fields: extendFields(['burned']) });
const res = await client.fetch(query);

const items = res.data.items;

assertEqual(items, items.filter(x => !x.burned))
```
