`?crate` command causes new message when edited instead of updated/edited message

[ilyvion]

This ?crate message was edited three times, so we have got a total of four responses.

What I would have expected is for the response to have been edited, like what happens with ?play and ?eval. Unless that's not possible for messages with a "fancy" reply, in which case editing the original should either be ignored or the original reply deleted and then re-posted.
