We have a hack in JSObject::getOwnPropertyDescriptor for DebuggerScope and ProxyObject.
But this is wrong since,

1. This hack breaks the assumption that JSObject::getOwnPropertySlot should return own property
2. This hack is only added for JSObject::getOwnPropertyDescriptor. So, the other clients using JSObject::getOwnPropertySlot see the different results
