Issue with $subscription->cancel

[beautifullife]

Hi author, thanks for this cool contribution to work with Stripe. It's work for me!
But I have a little issue in file yii2mod/yii2-cashier/models/SubscriptionModel.php line 328 in function cancel():

$subscription->cancel(['at_period_end' => true]);

I get an error that "at_period_end is not a valid param". I just change to $subscription->cancel(); And it work.

Same here. Have you found any workaround?

A workaround could be:
// $subscription->cancel(['at_period_end' => true]);
$subscription->cancel_at_period_end = true;
$subscription->save();

Hopefully, this will be fixed in a new version => #15
