Nasty fix to pass fixed cookie value in WP_Http_Cookie

plugin.php

<?php 
      //...
      // Replace space with + from cookie value
      // because WP_Http_Cookie does urldecode( value )
      // which is fucking wrong.
      $response['cookies'][0]->value = str_replace(' ', '+', $response['cookies'][0]->value);

      // Set cookies for the second request
      $this->cookies = $response['cookies'];
      //...
?>
