CMDHELPER-3044 - Reported by Pieter12345

Problem:
When json_decode() is called with an empty string (doesn't matter if it's a variable or just a string), it will return an error in core.

Error:
[16:20:20] [Server thread/ERROR]: Uh oh! You've found an error in Core.
This is an error caused while running your code, so you may be able to find a workaround, but is ultimately an error in Core itself.
The line of code that caused the error was this:
json_decode('')
on or around Interpreter:1.
Please report this error to the developers, and be sure to include the version numbers:
Server version: 1.8-R0.1-SNAPSHOT;
CommandHelper version: 3.3.1-SNAPSHOT.2837-;
Loaded extensions and versions:
CHDangerous (version 1.0.1);
Core (version 3.3.1);
SKCompat (version 1.0.0);
