Remove TreatNullAs=NullString for HTMLFieldSetElement

Remove TreatNullAs=NullString for HTMLFieldSetElement

http://www.whatwg.org/specs/web-apps/current-work/multipage/the-button-element.html#htmlfieldsetelement

The test passes only in Firefox Nightly, since neither IE11 Release
Preview nor Opera 12.16 supports the property at all, verified by
document.createElement('fieldset').name == undefined.

Updated the failing tests. In general, would you prefer that I wait until I have
green trybots before sending a review? In cases like this I've gone ahead with
the confidence that they will either pass or fail in ways which I can fix in
minutes.

If it's not too much trouble, green bubbles are great :)
