Fix local functions not affecting variables, again...

[NotHyper-474]

This is more of a provisional fix, since the current system is very susceptible to edge cases. It should probably be entirely reworked in the future. Also, sorry but I decided it was better off killing clone for this.

Obligatory test script to ensure nothing broke.

import funkin.modding.module.Module;
import flixel.util.FlxTimer;
import flixel.FlxG;

class Script1 extends Module
{
  function new()
  {
    super("script1", -99999);
  }

  var test:String = null;

  public override function onUpdate(event:ScriptEvent):Void
  {
    super.onUpdate(event);

    if (FlxG.keys.justPressed.ONE)
    {
      FlxTimer.wait(1., () -> {
        testFunc();
      });

      FlxTimer.wait(1.5, () -> {
        trace('Test in route 1: $test');
        test = null;
      });

      FlxTimer.wait(2., () -> {
        testFunc(false);
      });

      FlxTimer.wait(2.5, () -> {
        trace('Test in route 2: $test');
        test = null;
      });

      FlxTimer.wait(3, () -> {
        trace('Test at the end: $test');
        example1(() -> trace('Callback called!'), 67);
      });

    }
  }


  function testFunc(route1:Bool = true)
  {
    if (route1) this.test = toString() + ' 1';
    else test = toString() + ' 2';

    trace('${route1 ? '1' : '2'} - test set to $test');
  }

  public function example1(callback:() -> Void, obj:Dynamic):Void
  {
    FlxTimer.wait(1, function():Void {
      callback(); // errors saying it cant find "callback"
      trace(Std.string(obj)); // will also error saying it cant find "obj"
    });
  }
}
