Resolve UI unit tests performance issues and add tests run on push hook using husky

[Aviv-Galmidi]

We currently run the client tests using Jest. Jest has a known performence issue, see here: jestjs/jest#7963

We want to add a pre-push hook using husky to run our UI unit tests and abort the push on failed tests, but as the tests currently take over 7 seconds to start up it might slow-down the process for each push and end up not cost-effective (vs the current test run on PR using github)

If we find an alternative to Jest or somehow we manage to resolve the performance issue we can attempt to add the tests run to the pre-push hook

After further investigation, I could not find a significant improvement with mocha over jest. For the time being we'll leave it as is (Jest + Tests run on github actions)

If anything changes in the future we may visit this subject again
