Use of enum type causes schema builder to fail

If an Object Type is using a GraphQL enum, the schema will fail to build.

Here's an example schema:

enum Foo {
    Bar
}

type Model @model {
    id: String!
    foo: Foo!
}

Here's the error in the console:

fail: Microsoft.AspNetCore.Server.Kestrel[13]

Start by reproducing the failure with the GraphQL schema shown in the issue and inspect the schema builder path around the unresolved FooOrderByInput type. No source or test file is named; done means the schema builds successfully when an object type uses a GraphQL enum, with coverage for this example.
