wxLang: only load language data if the given UI language has language info. Re #9089. (#9092) 2018.4 regression: wxLang.Language fails in Aragonese because wxLang itself is None. There might be other languages where this might be the case. Thus only obtain wxLang.Language if and only if wxLang is indeed not None.
