Add autotest to test a issue with stretches and preferred width.
The issue seemed to claim that the preferred size was not respected
when there was another item that could stretch along the same axis:
"A widget with a horizontal stretch next to it should get its
preferredWidth()".
This seems to works as expected, so nothing to fix.
Task-number: QTBUG-12835
