Ensure OutputPageTest works when Translate extension is loaded

The translate extension registers the LanguageLinks hook which is run by
OutputPage::addParserOutputMetadata with a Title as an argument.  If
our mock doesn't provide a valid Title, then
PageTranslationHooks::addLanguageLinks() in Translate will throw a
TypeError in OutputPageTest::testParserOutputCategoryLinks().
