last snap schedule delete fails

Description of problem:
when multiple schedules defined for a path and with retention policy having monthly interval, deleting of schedules gets stuck for the last one. Even upon many attempts, delete doesn't succeed from Dashboard, however delete is allowed from cli.

Error in Dashboard mentions "Failed to remove Retention policy for path <> Retention for m:3 was not set for <path> can't remove"

There is a fix mentioned in MR: https://gitlab.cee.redhat.com/ceph/ceph/-/merge_requests/537

"Added call to remove retention policies when removing a snap schedule
in case it is the last one with same path"

The scenario I have been trying is very similar to workflow mentioned above.So guessing the change in this MR is causing the issue.

So adding the Regression keyword, please update/remove if not appropriate.

Version-Release number of selected component (if applicable): 18.2.1-105.el9cp


How reproducible: consistently


Steps to Reproduce:
1. Create 3 snap schedules for same path, with schedule as Monthly and hourly
2. Add relevant retention policies mentioning retention period for Monthly and hourly intervals
3. Verify schedules are created as expected.
4. Delete the schedules in an order.
5. Verify if last schedule in list for same path can get deleted in Dashboard

Actual results: Last schedule deletion fails with error described above.
Attached screenshot has error details.


Expected results: Lash schedule deletion should have succeeded.


Additional info: When issue is hit, schedule deletion from cli succeeds. May be because in CLI, we have a cmd syntax to delete schedule by specifying path only.
