QTreeView: make sure to not ask the old model during setModel
Within QTreeView::setModel() the header might emit columnCountChanged
which then tries to update the geometries based on the old model which
is wrong.
Fix it by setting geometryRecursionBlock to true so
QTreeView::updateGeometries() will not ask the old model for it's data.
Fixes: QTBUG-75982
