elm: [atspi]enhance _accessible_at_point_top_down_get

If there is only one valid child at point, then return it.
The evas_tree_objects_at_xy_get could not find proper object,
if application does not have well aligned objects.

This could be a role of application, but this patch set could solve somehow.
