Delete the test mod crashing dedicated server

I downloaded the library and noticed that the test mod doesn't work anymore, so I removed it as it crashes the server when loaded and could cause problems to devs (I took 1 minute to figure it out but some inexpert modders could think they're doing something wrong)

The crash log for reference:

    Exception in server tick loop
