Remove TreatNullAs=NullString for URLUtils.href

http://url.spec.whatwg.org/#urlutils

The updated element-attribute-js-null tests pass in Firefox Nightly,
IE11 Release Preview and Opera 12.16.

No other browser passes the URL.href test, because Firefox throws when
setting a non-valid URL, while IE and Opera don't even support the URL
constructor.
