bug #5067 :  The locked documents aren't automatically unlocked according to the nbDayForReservation parameter

The path of the English bundle wasn't correct so its loading throws an exception, causing the failing of the process of the unlocking of documents. Beside that, in order the unlocking date matches more correctly the value of the 'nbDayForReservation' application parameter, the cron of the scheduling of the unlocking process is now planed to every days at 00H01.
