Adds the given href to this response. If <code>setHref(String)</code>
hasn't been called and no hrefs have been added, this method sets
the first href and is thus equivalent to
<code>setHref(String)</code>. The href must not be <code>null</code>.
This response must not already be in "propstat" form.

@param href the href to add
