[Unit Tests] Get test:watch working again

[unlikelyzero]

Summary

At some point, the test:watch npm script was broken. Let's get it working again!

I was looking into this a little bit earlier today, and I noticed that running test:watch causes karma to run the tests over and over again in a loop (it keeps detecting file changes). Is this the broken state of which you speak?

Running it in verbose mode, karma says it keeps detecting file changes after each test run has completed. So I wonder if some files are being watched that shouldn't be?

@ozyx this doesn't have any priority right now, but that's the behavior that I just saw. I haven't used it before so it's possible that it hasn't worked for years

Testing Notes

Run test:watch and verify that the tests are retriggered ONLY when modify the testcode or the application code
npm run test:watch

Not Fixed Locally: Testathon: 7/8/22

This looks to be running in a loop...

Testathon 7/11/22: confirmed looping when run locally
