[IMP] website_sale_slides: ensure login after purchase

Purpose
=======
If we buy a course without being logged in, we are redirected to a page
with a button "Start Learning". That button redirects to the course we
just purchased. Instead, we want to redirect the users to the login page,
and after that to the course page.
