While dragging assets over a catalog, we would show both the name and
the full catalog path in the drag tooltip. For catalogs at the root
level (catalogs without parents) the name and the full path are the
same, so it would just display the name twice. This is more confusing
than helpful. Now skip displaying the full path in that case.
