[Qt-qml] Avoid binding warnings on object creation

I think this is the same problem I was facing.

I created a suggestion in JIRA related to this behavior:
http://bugreports.qt.nokia.com/browse/QTBUG-13170

The problem is that when creating an object dynamically, the parent is
set after all properties have been initialized. So, the parent itself
does not exist at the initialization time.
