This exposes all fields named `id` as GlobalIDs so they can be used across our entire GraphQL implementation. When the objects loaded are `ApplicationRecord`s. We'll use our existing batchloading to find them. Otherwise, we'll fall back to the default implementation of `GlobalID`: Calling the `.find` method on the class.
