Fixes NV#2 (calling removeClass() with no arguments does not remove all classes).

jQuery's behavior changed somewhere between 1.4.4 and 1.11.3; the 'empty' test
case works against 1.4.4 but not 1.11.3 or 2.1.4.  Changing the fallback case
to pass along the original arguments verbatim fixes the issue.
