An issue in the code prevented the SameSite session cookie option from being set the first time we were reaching SSP when using PHP versions older than 7.3.

This fixes #1320

* fixed warning when Warning: session_create_id(): Failed to create new ID in /var/ssosp/lib/SimpleSAML/SessionHandlerPHP.php

* Use session_create_id() unconditionally

In master, we require PHP 7.2, which is guaranteed to provide `session_create_id()`. Therefore, we don't need the if clause any longer. Add also a warning when `session_create_id()` fails, and fall back gracefully to our old way to create session IDs.
