Run Wasm tests in workers as well (#552)

This change runs Wasm tests in workers as well.

- Fix Node tests not actually running any tests. It was already broken
because of an interaction with the latest Rust version and an old
Node.js version.
- Test dedicated, shared and service worker by using the newly added
environment variables: rustwasm/wasm-bindgen#4295.
