fix: deleteStatus doesn't work

The endpoint URL of statuses/destroy/:id API is like "https://api.twitter.com/1.1/statuses/destroy/240854986559455234.json".
cf. https://dev.twitter.com/docs/api/1.1/post/statuses/destroy/%3Aid

deleteStatus will pass no parameters by this change, so this change depends on https://github.com/geoffjentry/ROAuth/pull/6.
