TreeView: update currentIndex on model changes
The previous binding was not getting re-evaluated when the model was
being reset or when rows were been inserted or removed.
Here we use a counter variable, whose value change will force the
evaluation of the binding.
Fixes: QTBUG-53097
Change-Id: I76afebbda78ab477cf65631337a8bad51ca5428d
