[Quick 9.0.2] Calling Relationship Setter on HasManyDeep (HasManyThrough) Throws Exception

[homestar9]

Issue:
Calling relationship setter on a HasManyThrough (HasManyDeep) relationship will throw the exception:
"Method does not exist on QueryBuilder [applySetter]"

How to Replicate:

1. Define a HasManyThrough relationship:

// Page entity 

// a `Page` has many `Category` through intermediate `PageCategory` entities
function categories() {
      return hasManyThrough( [ "pageCategories", "category" ] );
}

function pageCategories() {
        return hasMany( "PageCategory@cms", "pageId" );
}

2. Attempt to call the setter in your handler:

prc.page.setCategories( "1,2,3" );

Expected:
I expected the relationship setter to function like the other relationship types and persist the new categories via the PageCategory intermediate entity.

Actual Result:
Throws exception.

Workarounds?
None that I can think of unless you work directly with the intermediate entity relationship, but that creates complexity in your handlers or model, which I believe should be handled by the ORM.
