make sure QScriptContext::scopeChain() returns the right object

Follow-up to commit e0a86dc604b87921652b844a5f85889bb6291ed9.
Just like in the activationObject() function, we need to check if
the activation object is actually a proxy to another object, and
return that other object if that's the case (the proxy object should
not be exposed to the public).
