Write tests for the `useQuizResources` module

[nucleogenesis]

Overview

The quiz creation updates added a new useQuizResources module that extends an also-new useFetchTree module. useFetchTree has tests written for it but useQuizResources does not.

Acceptance criteria

There is no real need to test that the useFetchTree modules do what they're supposed to so they can likely just be mocked to return a suitable data structure.

• [ ] Test the annotateTopicsWithDescendantCounts -- see the comment above it to get a sense for what is supposed to be happening here.
• [ ] Test that this function is called on the data that is returned from both the fetchQuizResources and fetchMoreQuizResources functions
• [ ] Follows the guidance on testing https://kolibri-dev.readthedocs.io/en/develop/frontend_architecture/unit_testing.html

Hi @nucleogenesis could I take a look at this isuse?

Hi @oge1ata, thank you for volunteering, looking at the issue I think this could be open for contribution. It may help to spend some time looking at existing test suites, such as useFetchTree that @nucleogenesis referenced.

Hey @MisRob Thanks for the assignment. I'd take a look at it and tell you if I have any issues.

Hi @oge1ata, are you still planning to work in this?
