a11y: Remove AtkSelection implementation from combobox

AtkSelection requires that the immediate children of the object are the
selectable items. The combobox however is implemented with just 1 child:
The popup menu.

The popup menu is implementing the selectable interface.

Test are updated to reflect this change.
