ReportingPlugin (FactNotificationPlugin) - original exception should be visible when using Monitoring Interface

Current Situation

if error occurs when reading configuration files the ReportingPlugin (FactNotificationPlugin) raise error such as:

com.sos.jitl.reporting.plugin.FactNotificationPlugin [ERROR] - FactNotificationPlugin.init java.lang.Exception: skip notification processing due init errors

without an orginal error message.
If the JobScheduler configured to send mail on error - Reporting Plugin sends an error mail with the full stack trace and the original error can be identified from the stack trace.

Desired Behavior

The original error message should be logged.
