Prysm: ERROR pool/attestations: Cannot delete seen attestations error=<nil>

🐞 Bug Report

Description

Users are seeing an error message for a nil error after deleting seen attestations.

ERROR pool/attestations: Cannot delete seen attestations error=<nil>

https://github.com/prysmaticlabs/prysm/blob/572227d25e5c76b6f662e9713aedb7b0c668e6eb/beacon-chain/operations/attestations/prune_expired.go#L38-L40 This is not an actual error, but a mistake in the if statement. The line of code should check `err != nil` but does the opposite. :rotating_light: **Users experiencing this error may safely ignore the message for now.** :rotating_light: ### Has this worked before in a previous version? Yes. ## 🔬 Minimal Reproduction Run any beacon chain with alpha.25. ## 🔥 Error
