Describe the bug

When applying a scope to the morphTo directive, it appears that Lighthouse is trying to apply the scope to the root model, rather than then target relationship. For instance, given the following schema:

type Author {
    id: ID!
    publications: [Publication!]!
}

type Publication {
    id: ID!
    publication: Publishable @morphTo(scopes: ["active"])
}

type Magazine {
    id: ID!
    title: String!
    isActive: Boolean!
}

type Book {
    id: ID!
    title: String!
    isActive: Boolean!
}

union Publishable = Book | Magazine

Lighthouse is trying to apply the active scope to the Publication model, rather than the Magazine or Book model.

Expected behavior/Solution

The scope should be applied to the query responsible for fetching the Magazine or Book.

Steps to reproduce

See above example.

Right, the current behaviour is somewhat nonsensical. To properly support scopes on polymorphic relations, the definition has to take the type of the related model into account. I got a PR on this going, but it needs a bunch more work to be finished. @dennis-koster please review #2110

@spawnia Hi Spawnia, thanks for drafting up a PR! I think the idea of specifying which model you want to apply what scope(s) to makes sense. I wonder if this would work in combination with the union type though, as in my example. Perhaps it would be beneficial to add a test for that scenario as well.
