Change the life cycle state of a deleted folder children to "deleted" too when using 2 parts packaging

Children of a folder are still in "project" or whatever state when a folder is removed.
This is only happening in the two parts packaging (works ok otherwise) because the core listener performing this is on the stateless part.

=> nuxeo-platform-webapp-core/src/main/java/org/nuxeo/ecm/webapp/lifecycle/BulkLifeCycleChangeListener.java should be moved to a module that is deployed on the stateful part.
