Fix: Players don't auto-send emoji replies when donated to, unlike nations (openfrontio#2808)

## Description:

The new (awesome) nation emoji updates had a small bug in them when I
was playtesting with a friend where donating troops to them (a human
player) would result in the player automatically sending an emoji reply.
Sometimes these replies were negative-connotations like ❓ and 🥱, which
could impact how other players perceive their donation attempt. This PR
fixes that issue.
