remove automatic setup of tokenizer directory

ICU tokenizer doesn't need any extra data anymore, so it doesn't
make sense to create a directory which then remains empty. If a
tokenizer needs such a directory in the future, it needs to create
it on its own and make sure to handle the situation correctly where
no project directory is used at all.
