Update class-fw-session.php

PHP sessions created with session_start() function may cause issues with REST API and loopback requests due to cURL error 28. According to recommendations of WordPress core team active PHP session should be closed before making any HTTP requests

Hi Franck,
do the flash messages work well in the frontend and in the admin?
By docs of this function session_start I see that using this flag close the session file so we can't put anything there

In addition to the normal set of configuration directives, a read_and_close option may also be provided. If set to TRUE, this will result in the session being closed immediately after being read, thereby avoiding unnecessary locking if the session data won't be changed.

<?php
// If we know we don't need to change anything in the
// session, we can just read and close rightaway to avoid
// locking the session file and blocking other pages
session_start([
    'cookie_lifetime' => 86400,
    'read_and_close'  => true,
]);

I think there may be some trouble with flash messages
Can you have a look if they are working?
