Change Details

Also: - unify with other `_fix` methods to work on one origin_visit (and not a list) - Add test cases around such scenario - clarify the crash behavior which is an expected one. If an origin_visit is too old (without type), this is unexpected. So the replayer must crash and we must fix the journal's origin_visit topic. This now definitely says as much in the code.

This aligns with what's done for the other object types. Also: - Add missing test cases around existing scenario - Clarify intent about stopping the replayer when an old origin_visit format is detected.
