Title: Fix Tokenizer::Base#traverse. Avoid exceptions.

Fix for [this](https://github.com/twitter/twitter-cldr-rb/blob/master/spec/tokenizers/base_spec.rb#L110-112) test case. The downside is that we limit valid tree nodes to the instances of the `Hash` class. Though, if that's acceptable, I think this solution is better than the original one that blindly rescue every `NameError` exception (btw, is `NameError` the exception that should be rescued here?).
