xml: Fix parsing of default namespace with quoted names

* lisp/xml.el (xml-parse-attlist): Properly extract namespace when
  parsing is done with quoted symbol names (bug#23440).
* test/lisp/xml-tests.el (xml-parse-test--default-namespace-qnames)
  (xml-parse-test-default-namespace-qnames): Test for the above.
