Title: Support iteration with manually called next()

Currently, if one calls `next()` method on tweet iterable, it raises exception, because `_nextTweet` is defined in `__iter__()`. I fixed it and also moved the check of `__response` existence to `next()`, so it raises `'No results available'` exception, if there's no response.
