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.
