Stabilize test of QSpinBox.

The test shows spurious failures in editingFinished() on some Mac
platforms (QTest::qWaitForWindowActive(testFocusWidget)).
This is apparently caused by the widget testFocusWidget (member
variable) interfering with the other tests widgets.
As it is used in one test only, instantiate it on the stack there.
