Put lifetime variable back in the session testcase
Put lifetime variable back in the session testcase

A PR in Laravel added session lifetime into 5.2 and 5.3 for the CsrfToken middleware (https://github.com/laravel/framework/blob/5.2/src/Illuminate/Foundation/Http/Middleware/VerifyCsrfToken.php#L137) https://github.com/laravel/framework/pull/14080/files
(This needs to be merged into the 3.3 branch as well.)
