Fix leak in get response

PHP 7 has done away with the third argument to RETURN_STRINGL
(where one could decide if the string was to be duplicated or not)
meaning that we now need to free our response as RETVAL_STRINGL
will duplicate the string.

I'm not sure what the proper solution is for this in php7
