[FIX] Fix calling instance inline functions of abstracts

[lemz1]

This pr fixes inline abstract functions that assign to this directly.

script.hxc:

import flixel.FlxBasic;
import flixel.util.FlxColor;

class TestScriptedClass extends FlxBasic {
    public function new() {
        super();

        var color = FlxColor.RED;
        trace(color);
        FlxColor.setRGB(color, 255, 255, 255, 255);
        trace(color);
    }
}

before:

hscriptClass(mods/introMod/script.hxc):9: -65536
hscriptClass(mods/introMod/script.hxc):11: -65536

after:

hscriptClass(mods/introMod/script.hxc):9: -65536
hscriptClass(mods/introMod/script.hxc):11: -1

HashOrArray seems to not work with the type parameter being Dynamic
