Issue description

It would appear that the onPlayerInteractBlock event fires 4 times on a single right click. The script below is enough to reproduce the effect.

Steps to reproduce

Load up an instance of 1.12.2 on the latest forge and crafttweaker with the script and right click any block once.

This is normal, Forge fires the event 4 times like so (not in this exact order):

1. Once on the server for the main_hand
2. Once on the server for the off_hand
3. Once on the client for the main_hand
4. Once on the client for the off_hand

The "solution" to make it only fire once is to do:

import crafttweaker.event.PlayerInteractBlockEvent;

events.onPlayerInteractBlock(function(event as PlayerInteractBlockEvent){
    if(event.world.remote || event.hand == "off_hand") {
        return; // If it is on the client or the off_hand, do not continue.
    }
    event.player.sendChat("Hello I'm firing!");
});
