Is there a reason why [`objectifyId()` only converts an id if the id field is `_id`](https://github.com/feathersjs/feathers-mongodb/blob/c8769695ceebb1fc7848cb5b519943d2b6f30544/src/utils.js#L26)? This currently makes it impossible to use an ObjectID in another field as the primary key.
