fixes https://linear.app/tryghost/issue/ENG-1484
- in Ghost release
[v5.89.0](https://github.com/TryGhost/Ghost/releases/tag/v5.89.0), we
have added a safeguard around bulk member deletion, due to a limitation
in NQL for member filters (commit: 2484a77)
- with this change, we limit the safeguard to only the cases we know are
problematic, and remove it for other useful and safe queries
- more precisely, the safeguard is in place only when:
- Multiple newsletters exist, and the filter contains 2 or more
newsletter filters
- If any of the following stripe filters are used even once:
- Billing period
- Stripe subscription status
- Paid start date
- Next billing date
- Subscription started on post/page
- Offers
