Elide the explicit any namespace prefix when lacking default namespace.

Browse source 
Once again it seems we don't need to preserve the original prefix name,
and this lets to_css serialize to the shortest form when there is no
default namespace and the *| prefix is used.

Selectors § 6.1.1 says:

    Element type selectors that have no namespace component (no namespace
    separator) represent elements without regard to the element's namespace
    (equivalent to "*|") unless a default namespace has been declared for
    namespaced selectors (e.g. in CSS, in the style sheet). If a default
    namespace has been declared, such selectors will represent only elements
    in the default namespace.

Then if there is no default namespace, *| (which we write as
QNamePrefix::ExplicitAnyNamespace) is equivalent to what we write as
QNamePrefix::ImplicitAnyNamespace; the latter has a shorter
serialization, so we should use that.
