a11y tests: Make combobox focus tests more reliable

The combobox focus test was occasionally (in 2 out of 20 runs)
failing in my setup with with QT_QPA_PLATFORM=xcb as follows:

    1: FAIL!  : tst_QAccessibility::focusChild() 'QTestAccessibility::containsEvent(&focusEvent)' returned FALSE. ()
    1:    Loc: [.../qt5/qtbase/tests/auto/other/qaccessibility/tst_qaccessibility.cpp(4606)]

Wait for the combobox to actually have focus before
checking for the a11y event.
