resolve #86

This will work only with newest doorkeeper version. We have either change version in the gem spec either add support for old im0lementations as well

@nbulaj

Thanks for your review 😄
I simply add keyword arguments, include_expired, with a default value. The new feature I added is only called when this argument is sent. So I think It is not a problem for doorkeepers with old versions, right?

Yeah, I hope so.. Maybe internals are using matching_token_for but since kward has a default I hope it will be OK to use it with old gem versions as well. Thanks!
