[appserver-io/doppelgaenger] Endless recursion on parent::<METHOD> call

A constellation such as:

``` php
class A {
    public function test(){}
}


class B extends A {
    public function test(){
        parent::test();    
    }
}
```

does result in an endless recursion as method proxies are prone to the override mechanism.
Therefor the parent original implementation never gets called as the parent proxy does call the child original method instead.
