Currently the language for the stemmer is inferred using name(language(d)) where d is an ::AsbtractDocument. This produces the name of the language in that language (e.g., "русский" for Russian). Snowball stemmer, however, requires it be in English or as an ISO code:
[...] The algorithm may be selected using the english name of the
language, or using the 2 or 3 letter ISO 639 language codes. [...]
This PR fixes it by using english_name instead of name, thus producing, e.g., "russian" instead of "русский".
