Server logs "Game test server" messages

The bug

In 22w17a two methods in net.minecraft.server.MinecraftServer were overridden to log the following messages:

• "Game test server crashed"

• "Game test server shutting down"

MinecraftServer is the base class for all server types, however these logged messages seem to be specific to the internally used 'game test server' (net.minecraft.gametest.framework.GameTestServer) and should probably only logged for that class.

Reproduction steps

1. Start the dedicated server

2. Make the server crash, for example with MC-250919 (note that Watchdog crashes won't trigger this log message)

3. Look at the log file
   ❌ The following was logged

   [02:47:04] [Server thread/ERROR]: Game test server crashed
