BUGFIX: Throw on duplicate derived model names

[unclecheese]

Resolves: #403

I get an infinite loop somewhere when running a (web) dev/build?flush after this change - I’ve narrowed it down to this PR.

I do have a duplicate derived name, which I was working around with this:

SilverStripe\GraphQL\Schema\Schema:
  schemas:
    admin:
      config:
        modelConfig:
          DataObject:
            type_mapping:
              App\Model\Page: AppPage

I tried removing that, but I still get an infinite loop rather than a warning about duplicate names 😞

Can you move that type_mapping to the main schema config, eg config.yml and use "typeMapping" instead?

So the config in e.g. app/_graphql/config.yml? It’s for the admin schema though, so will that work or will I have to set up a second config directory for the admin schema? I’ll give it a shot tomorrow, thanks!

Okay that does fix it:

SilverStripe\GraphQL\Schema\Schema:
  schemas:
    admin:
      config:
        typeMapping:
          App\Model\Page: AppPage

I’ll create an issue for the infinite loop thing. Thanks and Merry Christmas @unclecheese 🎄
