Updated member bread service to return member subscription offers from offer_id column (#392)
Updated member bread service to return member subscription offers from offer_id column (#392)

refs https://github.com/TryGhost/Team/issues/1520

- Instead of doing the matching of the offers and subscriptions by looking at the offer redemptions, we can now look at the offer_id from subscriptions.
- This also fixes an issue where we don't attach the offer object to subscriptions in the members' browse method
- Updated browse behaviour to match the read behaviour of members (product relation needs to get loaded because it is missing in member.products if the subscription is expired).
