    tests, stacking: Add tests with no-input and no-take-focus windows
    
    When a window with no frame, that doesn't accept focus and that has no
    take-focus atom set is destroyed, we ended up in not changing the current_focus
    window, causing a crash.
    
    Added test cases that verify this situation.
