Stabilize the QHeaderView test.

The test has a member QWidget *topLevel which it recreates
and shows in init() without waiting for it to be exposed
although it is not used in every test case. This apparently
interferes with some tests that create separate top levels.
Do not show in init(), delete the topLevel.
Add wait to the cases where the topLevel is shown.
