* Improve test names.

Always sanitize user_nicename in wp_insert_user().

Previously, a 'user_nicename' parameter passed into the function was
unsanitized. This could result in a mismatch between the sanitized nicename
generated automatically at user creation, resulting in broken author archive
permalinks.
