Accessing related object not in the store

If I have users that have many books, and I make a request for a user object without sideloading the related books, then I might have the following structure in my store:

{
    users: {
        '1': {
            id: '1',
            type: 'users',
            attributes: {},
            relationships: {
                books: {
                    data: {
                        [{
                            id: '1',
                            type: 'books'
                        }, {
                            id: '2',
                            type: 'books'
                        }]
                    }
                }
            }
        }
    },
    books: {}
}

If I run const user = build(state.entities, 'users', '1') then I get the user back. However if I then run user.books I get [null, null]. I would expect that I should get

[{
    id: '1',
    type: 'books'
}, {
    id: '2',
    type: 'books'
}]

I have experienced many use cases where I don’t need the full related object, just the id (to provide a link to that object, for instance) and so I won’t include the related resources.

I’d be happy to make the changes if you would accept a PR!

Thank you for your contribution and kind words 😃

Thanks! Btw, I’m loving this library (and json-api-normalizer). It’s really cleaning up our implementation of JSON API!
