Duplicate messages in #🔔-meetup-notifications

[Aprillion]

For unknown reasons, there are duplicate messages for a start of a meetup event, e.g.: https://discord.com/channels/715220730605731931/812071027617824798/849312679549075486

There might be 2 instances of the bot or maybe there is a bug to cause sending 2 notifications (could be related to recent change that allowed multiple actions after message edit, but maybe not).

I think that's because edits don't have any connections to precious actions and don't update/delete previous side effects.
