list_render: Extend test to verify that list sorting is case insensitive.

The alphabetic sorting of lists in the User/Organization settings was
changed in fa0a5ec to be case insensitive.
This commit makes changes to the list_render.js test to verify that the
sorting of these lists is indeed case insensitive.
