#2777 Fix for - MonitoredItem2.OnReportEvent Ignores Session in ISystemContext During Notification Process

[Filippo-Oliva-ABB]

Proposed changes

Check the Session included in the ISystemContext instance, if any, and compare it with those belonging to the monitored items. If the ISystemContext instance contains a Session, the event will be appended only to the monitored items belonging to the same Session. If the ISystemContext instance does not contain a Session, the event will be appended to all monitored items, regardless of their sessions.
