The JcrObservationManager doesn't filter local/nonLocal events correctly

When adding an event listener to a session, if the noLocal filter is set to true, this listener shouldn't be notified with events generated from the "owner" session, but should be notified with events generated from the other active sessions.

This is not working atm. because of the fact that the processId of all the events in the system is the same for all active sessions, meaning there is not way to tell which event set belongs to which session.
