Fixes repeat question on shuffle

[chyke007]

There is an issue when the shuffle is enabled in the Quiz component. It repeats questions, this is happening due to the view not re-rendering when the shuffleQuestions function is done shuffling the questions, so the old question still happen to be in the view.

Example:

This repeats again as Question 5:

Looking at the result page shows that the new shuffled questions. We can see question 1 correctly displayed

This fix resolves the issue by rerendering the Core view and updating the active questions.

  useEffect(() => {
    setActiveQuestion(questions[currentQuestionIndex]);
  }, [questions]);

i think we can just combine it with L42 - L44.

useEffect(() => {
    setActiveQuestion(questions[currentQuestionIndex]);
  }, [currentQuestionIndex, questions]);

Done
