fix: pipe functions in projections

[okj579]

This fixes pipe functions inside object projections, like the query below:

const input = `*[_type == "user"] {
    name,
    refs[]-> | order(name)
}`;
const dataset = [
    {_id: '1', _type: 'user', name: 'Michael', refs: [{_ref:'1'}, {_ref:'2'}]},
    {_id: '2', _type: 'company', name: 'Bluth Company'},
];

Thanks! Sorry it took so much time, wanted to make sure we had test coverage for this case
