Sometimes we might want to know only what items are part of a collection, and we don't care about the values of those items. For this, we can populate the collection only with references:
```ts
const book1 = await em.findOne(Book, 1, { populate: ['tags:ref'] });
console.log(book1.tags.isInitialized()); // true
console.log(wrap(book1.tags[0]).isInitialized()); // false
// or alternatively use `init({ ref: true })`
const book2 = await em.findOne(Book, 1);
await book2.tags.init({ ref: true });
console.log(book2.tags.isInitialized()); // true
console.log(wrap(book2.tags[0]).isInitialized()); // false
```
Closes #1158
