2 typeholes in the same file can cause duplicate interface names

[Riku Rouvila]

Not a huge issue in this example as the interfaces are identical and the second one is merged with the first.

interface Bar {
  number: number;
  title: string;
  duration: number;
  audio_file: IAudioFile;
  published_at: string;
  long_description: string;
}
interface IAudioFile {
  url: string;
}

interface AutoDiscovered {
  number: number;
  title: string;
  duration: number;
  audio_file: IAudioFile;
  published_at: string;
  long_description: string;
}
interface IAudioFile {
  url: string;
}

export default function Episode(episode: Episode) {
  const foo: Bar = typehole.t1(episode);
  const bar: AutoDiscovered = typehole.t2(episode);
