The reason for this is that Gauss() configures LHCbApp() in which IOHelper() creates by default
EventDataSvc("EventDataSvc"), which means that we can no longer create
HiveWhiteBoard("EventDataSvc") unless the former one is removed.
This happens when
EnableHive=True is set in Gaussino, but
EnableHive=False is set for LHCbApp().
To be removed when Gauss() stops using LHCbApp()
