QQuickTreeView: be able to expand rows that are not yet visible in the viewHEADmaster

If the app expands a row in TreeView, that row will for a brief moment
be expanded in the proxy model, but not in the view, until the
view is polished. For that reason, when determining if a row can be
expanded or not, we should check the state of the proxy model, and
not the view.

Note: if the application needs the state of the view to reflect the
state of the proxy model immediataly after a call to expand,
forcePolish() is always possible.
