Fixed a regression where listeners subscribing to attribute change events
with additional args, would see their args shifted, when the attribute
was `set` with additional options.

e.g.

   foo.after("myAttrChange", function myListener(e, myCustomArg) {
      ...
   }, context, myCustomArgValue);

   foo.set("someAttribute", 20, myCustomOpts);

myListener would see [e, myCustomOpts, myCustomArg] instead of
[e, myCustomArg] in it's arguments list.
