Issue Description:

Startup log spammed with NoSuchMethodException errors when using only EnderIO/EnderCore with Forge-1.12.2-14.23.4.2747

What happens:

Startup log displays
[Server thread/WARN] [FML]: The declared version check handler method checkModLists on network mod id enderio is not accessible
followed by a NoSuchMethodError:
java.lang.NoSuchMethodException: crazypants.enderio.base.EnderIO.checkModLists(java.util.Map, net.minecraftforge.fml.relauncher.Side)
and iterates through the same WARN statement and NSME for all EnderIO integrations/powertools/etc.

What you expected to happen:

Server starts up with EnderIO and EnderCore active with no errors

Steps to reproduce:

1. Install forge server into folder on desktop using forge-1.12.2-14.23.4.2747-installer-win.exe
2. Add EnderCore-1.12.2-0.5.37.jar and EnderIO-1.12.2-5.0.31.jar to mods folder
3. Start server with batch file:

@echo off
java -jar forge-1.12.2-14.23.4.2747-universal.jar nogui
pause

4. On startup, NSME and WARN statements spam the log
