Title: Delete self._form along with everything else on redirect

When posting a file to a url that does a redirect I was getting this error from request:

You have already piped to this stream. Pipeing twice is likely to break the request.

The post callback would never get fired. When I deleted self._form it fixed the issue and I think it makes since its already deleting self.body etc.
