New project template does not have working Jest config

Issue summary

When creating new project with this template, tests generated for header component do not pass. It seems that TypeScript config is messed up when running Jest, as process errors out on first type declaration in the component

Details

    SyntaxError: [...]/src/components/header/index.tsx: Unexpected token (5:12)

Steps to reproduce

• preact create typescript projectName
• cd projectName
• npm run test

Additional information

When creating new project with widget-typescript template, Jest tests work just fine, but it seems they have different configuration.
