When a user is issued a refund in Chargebee the subscription does not fire a cancel webhook

[zachaysan]

Describe the bug

When a user is issued a full refund, the subscription webhook does not fire, so subsequent cancelation of the user failed. This is atypical behaviour, and so far only a single internal Flagsmith staff had the issue raised when he was testing the workflow.

To Reproduce

Steps to reproduce the behavior:

1. Create an account and pay for it with a credit card.
2. Get a Flagsmith Chargebee staff user to issue you a full refund.
3. Delete your user account and watch the 500 error through the Chargebee failure, since the Subscription is no longer cancelable as it has been issued a full refund.

Expected behavior

Either capture a full refund webhook, which should be possible, or add a get request to a subscription after failure to check if the cancelation had already proceeded in which case there should be no reason to fail the cancelation step.

@matthewelwell and I talked about this as a low priority bugfix, since we shouldn't see it with regular users.
