Fix crash when accessing QObject properties through activation object
Since objects in the scope chain have to be JSActivationObjects,
QScriptContext::setActivationObject() creates a proxy object that
should delegate access to the actual object.
This case was not handled in the toQObject() conversion function, so
for activation property access through evaluation (where the
this-object would be the proxy object, not the actual QObject), the
this-object conversion to QObject would fail, and the assert
"this-object must be a QObject" was triggered.
Task-number: QTBUG-21760
