  [beta][v16][rc1] Les contenus extra (pdf, epub, etc.) ne sont pas générés lors de la 2nde validation
  Version 16 RC1.
  
  Scénario de test : 
  - Je publie un tutoriel pris en zone de validation (J'ai pris celui sur les bases de la prog)
  - Le tutoriel est réservé, publié.
  - Je modifie le sous-titre du tutoriel et redemande sa validation (2 min après la première publication)
  - Je le réserver puis publie une fois de plus le tutoriel sans cocher la case maj majeur, donc en version mineure
  - Le tutoriel est publié cette fois, mais après 5 min, toujours pas de signe d'un pdf ni epub, etc.
