Avoid try…catch where if…else will do when using LanguageFactory

Browse source 
Needed for I869af06896b9757af18488b916211c5a41a8c563, where I am
trying to change LanguageFactory in MediaWiki core not to use
MWException.

Language::isSupportedLanguage() does not actually throw,
so this sigh can be one of relief.
