[FIX] website_slides_survey: fix some certifications issues in eLearning frontend

This commit fixes a few issues with courses which have certification

 * fix links to already passed certifications: currently it crashed, now it
   redirects to the certification end screen;
 * "Begin your certification now" green box link now has same behaviour
   as links in the list view. It redirects to either the start certification
   screen or the first slide in fullscreen mode. Moreover once the user has
   started the course (at least one completed slide) this box disappears as
   it is not really useful anymore;

Some dead code is removed.
