Title: Fix jQuery.noConflict

If there was no jQuery defined at all in the window, using `jQuery.noConflict` properly remove the `jQuery` and `$` references, but let them as `undefined` properties.

This fix, completely remove the keys. In the chrome console for example, the `$` reference, is then properly reset to the chrome console `$` utility.
