Codegen results in non-compiling Elm files

[Janiczek]

This is related to the Vendr repository as of commit 6eff9cc90cc.

When changing the ContractDetailInit query in ContractDetail/Api.gql, so that the ... on Contract case uses the fragment ...Contract instead of selecting fields manually:

query ContractDetailInit($id: ID!) {
  contract(id: $id) {
    ... on Contract {
      __typename
      ...Contract
    }
    ... on PermissionDeniedError {
      __typename
    }
    ... on NotFoundError {
      __typename
    }
  }

the codegen happens fine, but then the codegen'd Elm files don't compile:

Elm files failed to compile:

-- NAMING ERROR --- types/src/api/Page/ContractDetail/Api/ContractDetailInit.elm

I cannot find a `Contract_Contract_Details` variant:

145|                                 (Json.Decode.succeed Contract_Contract_Details
                                                          ^^^^^^^^^^^^^^^^^^^^^^^^^
These names seem close though:

    Contract_Contract

If this is too much / too little detail, let me know!
