Don't show the quiz pop-up twice (#3398)

* Avoid showing the quiz pop-up twice to the user

Due to the current flow of code it's possible that in
some cases the quiz pop-up is shown to the user twice.
This is unnecessary and unintentional.

So, change the logic in such a way that the quiz pop-up
would be never be shown twice to the user.

Fixes: #3281

* Quiz: remove unused parameters from methods

Some methods don't seem to be using the parameters that
they receive. So, just remove the unused parameters.
