Can't create relation based on id

[Techniv]

Hi!

Considering this models:

class A extends Model{
  static [Model.schema](){
    return {
      name: Joi.string(),
      ref: Model.hasOne(B)
    };
  }
}

class B extends Model{
  static [Model.schema](){
    return{
      name: Joi.string()
    };
  }
}

Considering I have on nodes in database:

(:B( id:"b1", name: "bar"})

If I create a new A like that:

let a = new A({
  name: 'foo',
  ref: {
    id: 'b1'
  }
});
a.save();

I get this:

(:B {id:"b1", name: "bar"})<--(:A {id:"a1", name:"foo"})-->(:B {id:"b1"})

The NeoDM id well considerate to create the relation but only the NEO_ID is used to determine if the node need to be create or not.
