Remove javascript URL case from <a>/<area>/Location hash setter

It makes no sense to just special case them in this IDL attribute
anymore, if it ever did. I cannot get a Location object to represent a
javascript URL so that case was a no-op and the other case should be
aligned with the URL Standard, which changes per
whatwg/url#254.
