Markku Heikkila 9e75354aab Fix crash in QTreeWidgetItem::sortChildren when adding new item. 
This is a cherry-pick of 4f388c383e39b598d997e21bd9a4f16d89bd0625
from February

Recursive call is caused if user code calls QtreeWidgetItem()::sortChildren and
sorting is enbled in QTreeWidget.

First call is from user code and second is caused by timer.
When timer expires second call is made.

This recursion is prevented with QTreeModel::SkipSorting skipSorting()
in QTreeWidgetItem::sortChildren();

Task-number: QTBUG-20345
