fix tc tests with the web worker

Current testing utilities don't like webworker scripts, even though my tests are running in real browsers.

The issue might be mocha or enzyme or karma

added medium label

added hard and removed medium labels

added blocked label

Maybe a way to do this is to conditionally export stuff based on whether or not karma is running.

Basically, detect if window.karma or window.__karma__ (not sure which one works now) exists. If it does exist, export some single-threaded stuff. If it doesn't, export the multi-threaded stuff. Could even export a flag so the code uses it a certain way.

Hopefully there's a better solution when I have more time

This has not just been fixed, I've also added tests that account for state updates and actually using the component that uses the worker stuff!
