Dom\NamedNodeMap::getNamedItemNS() passed the raw empty-string URI to
xmlHasNsProp(), which only matches NULL-namespace attributes when the
URI pointer is NULL, so lookups like getNamedItemNS("", "bar") returned
NULL while hasAttributeNS("", "bar") found the attribute. Normalize an
empty URI to NULL in spec-following mode, mirroring dom_get_attribute_ns()
in element.c; sibling audit of xmlHasNsProp()/xmlGetNsProp() call sites
found no other user-supplied URI paths.

Dom\NamedNodeMap::getNamedItemNS() passed the raw empty-string URI straight to xmlHasNsProp(), which only matches NULL-namespace attributes when the URI pointer is NULL, so getNamedItemNS("", "bar") returned NULL even though hasAttributeNS("", "bar") found the attribute in spec-following mode. This normalizes an empty URI to NULL at the namednodemap entry point, mirroring what dom_get_attribute_ns() already does in element.c, and adds a regression test covering both the legacy and Dom classes. Sibling audit of xmlHasNsProp() and xmlGetNsProp() call sites found no other paths that pass a user-supplied URI.
