[MC-253670] Server icon of most recently played multiplayer server replaced by Singleplayer world icon

Steps to reproduce:

attempt to join a Minecraft server
disconnect
open a singleplayer world
disconnect
go back to the multiplayer server list

the server icon is now replaced. It is possible that it is somehow saving the singleplayer icon over an existing icon in the multiplayer list. The exact details were that these servers were running an older version of the game (1.18, 1.17) and were not online at the time but this may still affect online servers running versions 1.19 or later.
