KRACOEUS-7599: Adds Updated By and updated timestamp to uploads.

If we aren't going to use the timestampDisplay we should remove it. You are somewhat breaking the intended separation between Narrative and NarrativeAttachment which was designed to prevent the attachment being loaded into the users session and therefore in memory forever. We have additional things to prevent that, and not sure what other places we pull this up anyway...can you look at using LegacyNarrativeServiceImpl.setNarrativeTimeStampUser instead?
