title: Stripe Subscription - Update expired subscription
body: <p>If a stripe subscription is cancelled and at_period_end is set to true, then the subscription will not be renewed and the customer will not be billed. After the date has passed the renewal date. What happens if I try to update the ended subscription? i am being lazy and do not want to first check if the subscription is active. I am hoping stripe will just reactivate the cancelled and expired subscription. here is the flow</p>
  
  <ol>
  <li>create subscription 1 month</li>
  <li>after 2 weeks, cancelled and at_period_end</li>
  <li>after 2 months, update subscription</li>
  </ol>
