fix(jqLite): make jqLite invoke jqLite.cleanData as a method

The previous implementation of jqLite didn't use cleanData from the jqLite
object but instead used a cached version which maede it impossible to
monkey-patch jqLite.cleanData similarly to how you can do it in jQuery.

The cleanData method is not meant to be called directly by userland code;
its purpose is mainly to be able to be monkey-patched; therefore, the previous
implementation didn't make a lot of sense.

This commit enables one of the tests so far run only with jQuery to run with
jqLite as well.
