MDL-48477 questions: no delete icon for only top-level category

Browse Source 
The back end code already threw an exception if you clicked the icon,
so you could not delete the category, but we should not have shown the
icon in the first place.

Thanks to Pramith Dayananda for working out the fix for this issue. I am
just committing it.
