* Roomserver input refactoring — again! * Ensure the actor runs again * Preserve consumer after unsubscribe * Another sprinkling of magic * Rename `TopicFor` to `Prefixed` * Recreate the stream if the config is bad * Check streams too * Prefix subjects, preserve inboxes * Recreate if subjects wrong * Remove stream subject * Reconstruct properly * Fix mutex unlock * Comments * Fix tests * Don't drop events * Review comments * Separate `queueInputRoomEvents` function * Re-jig control flow a bit
