upsertList not working on Windows

upsertList uses [LineStreamReader.php](https://github.com/akeneo/api-php-client/blob/master/src/Stream/LineStreamReader.php#L31) for response processing. Then LineStreamReader uses php constant `PHP_EOL` in order to detect multiple lines.
However, on Windows `PHP_EOL` is equal `\r\n` which breaks LineStreamReader.

Above issue occurs with configuration client - Windows <--> server - Linux.
