Duplicate type registration

[maximkrouk]

Is there any behaviour that relies on String(describing: type) in

// Sources/Graphiti/Definition/AnyType.swift

final class AnyType : Hashable {
	// ...
    func hash(into hasher: inout Hasher) {
        hasher.combine(String(describing: type))
    }
    // ...
}

It won't allow you to use nested types for your models like
ModelA.Response
ModelB.Response
And you will get an error

Duplicate type registration for GraphQLType "Response" while trying to register type Response

Using String(describing: type) will provide "ModelA.Response" string, .components(separatedBy: ".").joined() can remove the dot if needed. Should I submit a PR to support this stuff?
