Fixes an issue caused by a missing decorator.

Let's hope it's the only event of a missing decorator in the project. Otherwise it's good to go.

I think then more tests would fail.

looks like a compiler problem: storybookjs/storybook#9463

Yes:
appvision-gmbh/json2typescript#126

Upgrade to Angular 8 which supports TypeScript 3.5+ should solve the issue.

I will try to fix it in the d.ts files when I find out how.

I have already made a PR for the update to Angular 9: #172

For now, I have adapted package.json so that it does not update to json2typescript 1.3.0.
