Handle missing namespace prefix in XML dumps more gracefully

If an XML dump of a wiki is exported using dumpBackup.php, and there are
pages in a namespace that is not registered (perhaps because of a missing
extension), they will appear in the dump in the form

<page> ... <title>PageTitle</title> <ns>1234</ns> ... </page>

This caused the ForeignTitle code to raise an undefined offset error,
because it assumed that the <title> element was of the form
"Namespace:PageTitle" when <ns> was nonzero. This assumption is not valid.

Now, the importation of such dumps will no longer throw errors and the
pages will be correctly imported, although possibly to unexpected
locations.
