fixes https://github.com/TryGhost/Product/issues/3752
- Added some extra tests for edge cases
- Updated handling of multiple subscriptions so they are handled better
- Canceling a subscription when the member still has other subscriptions will now get handled correctly where the status and products of the member stay intact
closes https://github.com/TryGhost/Product/issues/3595
- when importing paid members with a coupon in Stripe, we currently
search for the corresponding offer in our database and attach it to the
subscription if found. However, if an offer doesn't exist in the
database, we do not create one and don't attach any offer to the
subscription
- with this change, we now support the creation of a new offer, based on
a Stripe coupon, if it didn't exist already

- when importing members via CSV, it's now possible to add the value "auto" for the "stripe_customer_id" field. When this option is passed, the importer will search for a Stripe customer based on the email address provided
- if there are multiple Stripe customers with the same email address, the customer with the most recent subscription is returned
As discussed with the product team we want to enforce kebab-case file names for
all files, with the exception of files which export a single class, in which
case they should be PascalCase and reflect the class which they export.
This will help find classes faster, and should push better naming for them too.
Some files and packages have been excluded from this linting, specifically when
a library or framework depends on the naming of a file for the functionality
e.g. Ember, knex-migrator, adapter-manager
