[FIX] website_slides: auto set done successfull quizz

For now, in no fullscreen mode, if the quiz is succeed, the
user progress is not updated because the quiz is not set
to done.
This commit implements this call to mark slide as done and
green the check bullet.
We decided to unify the submit RPC call with the done one,
so a quiz (or a slide with questions) can only be done when
submitting answers. As consequence, we need to prevent some
slide type to use the /set_completed route (quiz and certif).
