Session name cannot be empty, did you forget to call "parent::open()" in "Symfony\Component\HttpFoundation\Session\Storage\Handler\MongoDbSessionHandler"?.

The Laravel-MongoDB package currently integrates the Symfony MongoDB session handler. In Symfony, the session cookies are managed by the handler. It asserts the session is started before being destoyed.

https://github.com/symfony/symfony/blob/79ea49c772ce4b39f414cde5648ad347c3bbcfd7/src/Symfony/Component/HttpFoundation/Session/Storage/Handler/AbstractSessionHandler.php#L89-L93

But Laravel doesn't always open the session.

Solution: Implement a Session handler for mongodb in the Laravel-MongoDB package (1 class + tests)
