Delay `Unnamed Farmhand has joined.` until name is available

[JulianVallee]

Is your feature request related to a problem?

Currently, when a player connects to the server, the message Unnamed Farmhand has joined. is broadcasted immediately. However, this message is displayed before the player's entered his name, causing confusion and unnecessary noise in the chat.

Describe the feature

This issue should be resolved by delaying the PlayerIntroduction message until the name farmer was created.
