Populate doesn't work with refs

[stephenh]

I have a parent/child relationship but populate is not working because the child's mappedBy/ManyToOne is modeled with an IdentifiedReference.

I.e. in the child, I have:

  @ManyToOne({ entity: () => Parent, wrappedReference: true })
  parent: IdentifiedReference<Parent>;

When I try to preload the OneToMany collection on the other side of this relation (i.e. loading multiple Parents and using populate: ["children"], none of the Parent.children collections are populated correctly b/c this line is failing to match:

const items = children.filter(child => child[(prop.mappedBy)] as object === entity);

https://github.com/mikro-orm/mikro-orm/blob/master/lib/entity/EntityLoader.ts#L76

Because the child["parent"] is trying to match on entity, and entity is a Parent instance, but the child["parent"] field is an IdentifiedReference.

Thanks for the report. Will release this early next week.
