The subscription object here is a database model rather than an
ISubscription from the stripe library, and we need to 1) use the `get`
method to read attributes and 2) read the `subscription_id` attribute,
as the `id` is our internal one.
no-issue
If we receive webhooks out of order, e.g. a
`customer.subscription.updated` with a status of 'active', followed by a
`customer.subscription.created` with a status of 'incomplete'. We would
overwrite the correct value with data from the "older" webhook. This
ensures that we always fetch the latest data from the Stripe API before
storing in the database.
no-issue
This refactors the members-api module so that it is easier to test going forward,
as well as easier to understand & navigate. The Stripe API no longer contains
storage code, this is all handled via the member repository. And we have dedicated
services for webhooks, and stripe plans initialisation.
