Remove old references to timeslots

Sur la page tuteur/timeslots le bouton "Essayer" renvoie ceci :

Je ne sais pas si c'est normal, je suppose que non, mais j'avoue n'être pas sûre de savoir ce que ce bouton devrait faire.

added Bug Open for discussion labels

The timeslots is now completely managed by cal.com, so this page shouldn't exist anymore, and no links should redirect to it. I also think that the timeslots are still requested sign up, but it shouldn't.
