If a chunked body had valid chunks, but ended without a `0` in the final chunk (so, just `\r\n\r\n`), it would be parsed as a valid end. Now it will be rejected as the final chunk MUST be `0\r\n\r\n`. This was partially done before, but only if there were no chunks before the final. This fixes both paths.
