paytm gateway logout after callback laravel 7
#### Laravel 7 Changes
Our package is comptible with Laravel 7 but same_site setting is changed in
default Laravel installation, make sure you change `same_site` to `null` in
`config/session.php` or callback wont include cookies and you will be logged
out when a payment is completed. So inside your `config/session.php` update
return [
...
...
'same_site' => null,
...
...
];
