Test ejecting

[sverhoeven]

Functionality of create-react-app is to eject (npm run eject). After ejecting all the config files will be available from inside your application.

Need to test that after ejecting the Typescript modifications still work.

• [x] npm start
• [x] npm run build
• [ ] npm run lint
• [x] npm test
• [ ] npm test -- --coverage --no-cache
• [ ] Linting in VSCode
