ui/message.lua:53: attempt to index local 'message' (a nil value)

Looks suspiciously similar to #84

This is the commit we're on: 8dcfc7d

That's how it happened:

2023-05-09 13:47:47: ACTION[Main]: Server: Shutting down

I tried to reproduce with the steps above, but couldn't get it to crash again in the same way. Since a "new mail" is involved, it can't be a migration issue as suspected in #84
