    Force the deletion of the project from the DB when updating it
      When updating a project if we use the update method binding
      the current Project object to the one in the DB with the
      same filename, the update is successfull but all the childs
      of the stored project remains in the DB. Instead if we delete
      the project stored in the DB and we replace it with the updated
      one all the childs are deleted, and therefore the DB does not
      expand on each update
