Fix copy-pasted comment in deduplicator
Fix copy-pasted comment in deduplicator

The comment describing the early return case when a message was deduplicated based on its event ID was copy-pasted from the early return case where a message is deduplicated by its SHA-1 info hash. This change fixes the comment to avoid confusion.
