QmlDesigner: Evaluate properties for the root item in dummy context

Browse Source 
We evaluate properties for the root item in dummy context if
they contain "parent.".

Defining a parent in the dummy context was not working for QML 2,
because there seems to be a shortcut bypassing the metasystem for parent.

Task-number: QTCREATORBUG-15530
