fix(jqLite): correctly monkey-patch core jQuery methods

When real jQuery is present, Angular monkey patch it to fire `$destroy` event.

This commit fixes two issues in the jQuery patch:
- passing a selector to the $.fn.remove method (only fire `$destroy` on the matched elements)
- using `$.fn.html` without parameters as a getter (do not fire `$destroy`)
