Although #20394 suggested below, I think dupe persistentId can only be detected in ReplayFilter.

A better solution would be to detect the problem when the it first arises

Detecting dupe when:

• persistent actor is instantiated -> impossible, no global registry of persistentIds
• an event is journaled -> impossible, journals don't perform validation on persistentId
• ReplayFilter is called -> possible, but it needs to be turned on (mode != off)

However, the modified error messages got long because (partially my bad :| please suggest if they can be shorter) as we cannot be exact whether errors are from dupe persistentId or not.
