Tested both older and newer `native` clients.
To test newer clients, I sent a reaction message and everything worked as expected, I checked the DB and the reaction message had the `creation` column filled.
To test older clients, I checked out the commit with the release tag using `git checkout v1.0.172`. This is to test an older `native` client. Then I copied and pasted the necessary code in the `message-responders` file to demonstrate an updated keyserver, and when I tried sending a reaction message, everything worked as expected and when I checked the DB, the reaction message did not have the `creation` column filled which makes sense since no `localID` was passed
