Unit test/realtime account validation

[vnsrz]

Adds unit tests for the file realtime_account_validation.js, particularly on the password validation.

This was made for educational purposes.

Technical

To test the JQuery in the initRealtimeValidation method, a setup-jest.js file importing the $ identier had to be created and added to the package.json. As far as I know, this doesn't affect the other tests being ran, as they still passed.

Testing

Run docker compose exec web make test, there should be 17 tests running and passing now, as opposed to 16 before.

Fixed

[jimchamp]

Blocked by changes to the registration page: #7670.

[jimchamp]

Sorry for the delay, @vnsrz. This looks good to me. I'm removing the Jest setup steps that you have added, as similar code was added by #7962.

Some of the tests could be simplified with a second beforeEach call that sets the variables that are same and used by each test. I'll make some small changes to DRY the tests in another PR. Will mention you as a stakeholder so that you'll see what I mean.

Thanks for these new tests, @vnsrz! Apologies for taking so long to review them.
