Remove TreatNullAs=NullString for HTMLAnchorElement

The tests for the updated properties pass in Firefox Nightly, IE11
Release Preview and Opera 12.16, with these exceptions:

IE11 reflects coords as '0,0,0,0' and shape as 'rect', while it doesn't
support ping/download.

Presto doesn't support ping/download.
