Remove automatic setup of tokenizer directory

So far the tokenizer factory would create a directory for private data for the tokenizer and then hand in the directory location to the tokenizer.

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.
