Fixes #243 Tuples should no longer be squashed in the event store

Should this really be 0?

I just want to make sure, because this effectively means that the expiration time grabbed from parseExpiration will be the time since epoch that triggers the filter (currentMillis() - 0).  

This however seems different for the EventExpirationFilter which actually uses a real timestamp so the expiration time required in that metadata would actually be a ttl value.
