fix(deps): remove rubix' stemmer and its dependencies

[ChristophWurst]

Fixes #1037

Please see my comment here #1037 (comment) as I'm not a big fan of modifying dependencies (although it work in that case).

Using scoper would be cleaner, I think, but for now I have created nextcloud/recognize#1414 which should fix this
