Michael Sproul e282363669 Gracefully handle deleting states prior to anchor_slot (#8409)
Fix an issue detected by @jimmygchen that occurs when checkpoint sync is aborted midway and then later restarted.

The characteristic error is something like:

> Nov 13 00:51:35.832 ERROR Database write failed                         error: Hdiff(LessThanStart(Slot(1728288), Slot(1728320))), action: "reverting blob DB changes"
Nov 13 00:51:35.833 WARN  Hot DB pruning failed                         error: DBError(HotColdDBError(Rollback))

This issue has existed since v7.1.0.


  Delete snapshot/diff in the case where `hot_storage_strategy` fails.
