[HttpFoundation] NativeSessionStorage regenerate

Since session_start is called by the regenerate function, then the 'started' flag of NativeSessionStorage have to be set to true. Otherwise, the variable $_SESSION is initiated and the exception "Failed to start the session: already started by PHP ($_SESSION is set)." is thrown.

This can be reproduced by clearing the session data (cookies) before authenticating with a method that does not require csrf (eg. using the confirmation link of FOSUserBundle).
