I'm not positive if this a bug/regression or if I've been doing it wrong and need guidance on what the "right way" is. But I do have code that breaks when I attempt to upgrade to at least 1.5.0 where 46d9370 as added.

Simplified example:

await Person.query().upsertGraph({
  firstName: 'Jennifer',
  lastName: 'Aniston',
  parent: {}, // BelongsToOneRelation
});

In my case I'm dealing with a one-to-one for polymorphic attributes, but that shouldn't matter here.
What use to happen was two INSERTs would fire off, one for the primary object and one for the relationship. For the second, it would only insert the ID of the new primary object (plus any defaults).
However, as of 1.5, only the first INSERT is executed.

Regression or is there a better way to insert an "empty" relation in a graph?
