The actors are found fine after several GC rounds, so this is confirmed. Also, the migration now works as intended.

Manual testing:

Several GC runs prior to state migration:

2024-11-12T14:19:05.975826Z  INFO forest_filecoin::db::gc: filter keys for GC
2024-11-12T14:19:06.544906Z  INFO forest_filecoin::db::gc: GC sweep
2024-11-12T14:19:06.793863Z  INFO forest_filecoin::db::gc: GC finished sweep: 4189 deleted records

There are of course other errors that have to do with modifying the state migration epoch, but no bundle retrieval issues, I have also tested this before the persistent fix and it failed miserably trying to retrieve those from the DB.

Change checklist

• I have performed a self-review of my own code,
• I have made corresponding changes to the documentation. All new code adheres to the team's documentation standards,
• I have added tests that prove my fix is effective or that my feature works (if possible),
• I have made sure the CHANGELOG is up-to-date. All user-facing changes should be reflected in this document.

Follow-up issue - create common helpers to use for migrations and also for DB operations.
We have to duplicate the way that the keys are being constructed in several different manners, for e.g. EthMappings and the Graph. It would be nice to share the same code that is used by the application itself to avoid human error.
