Use Language::equals to compare Language objects

With I8a47a8500922906bd4e4936b59b657de3bb9abdc Language::equals can
directly and faster compare the objects.

$wgLanguageCode can differ from $wgContLang->getCode() when a deprecated
language code is used. This change prevents this because Language
replaces deprecated language codes in Language::factory().
