This is mainly testing this:

	if @brainstemKey == underscoredModelName && (@isNew() || @id == attributes.id)
	  @set(attributes)
	  collection.add(this)
	else
	  collection.add(attributes)

It was just a test to make sure that when the `brainstemKey` is the same on ourself and one of these results that unless `our id == the thing we're looping over's id` that it doesn't try to add our instance but creates a new one.
