ParserTest: clear Language namespaces cache

The content language object has a cache for namespaces, it might then
not take in account $wgExtraNamespaces set by the parser test suite
which causes unknown namespaces errors.

Ensure the new language object has a clean cache.

Repro:
php phpunit.php --filter '(ParserMethodsTest::testValidCovers|T53680)'
