    tests/stacking: Don't test for time-dependent intermediate focus state
    
    While c3d13203 ensured that the test-client has actually closed the
    window before testing for the focus change, it also made another timing
    related issue with the tests more likely to happen. Serveral tests
    assert that the focus is set to 'none' after the focussed window has
    been closed when the window below does not accept focus. This however
    can never be reliably tested, because closing the window triggers
    timeout based iteration of a queue of default focus candidate windows.
    This starts after the window has been closed and might finish before the
    clients have finished synchronizing. This issue is more likely to
    trigger the shorter the queue is and the more test clients there are
    that could delay the synchronization.
