Title: removed unnecessary else statements

I think that `self._write_buffer.append(data)` is unnecessary because when data length is smaller than `WRITE_BUFFER_CHUNK_SIZE`, `self._write_buffer.append(data[i:i + WRITE_BUFFER_CHUNK_SIZE])` in for loop just works as same as `self._write_buffer.append(data)` when i is 0.
