[cally] Fix a crash on some a11y examples if there isn't accessibility support

Browse Source 
Most of the accessibility tests can be executed without the
accessibility support, although it is clear that they will
not work properly (ie using accerciser).

But in some specific cases (right now just the atk event test),
the test will crash if no accessibility support is enabled
