Getting this error on a non-PeerDAS network:
```
May 29 13:30:13.484 ERROR Error fetching or processing blobs from EL error: BlobProcessingError(AvailabilityCheck(Unexpected("empty blobs"))), block_root: 0x98aa3927056d453614fefbc79eb1f9865666d1f119d0e8aa9e6f4d02aa9395d9
```
It appears we're passing an empty `Vec` to DA checker, because all blobs were already seen on gossip and filtered out, this causes a `AvailabilityCheckError::Unexpected("empty blobs")`.
I've added equivalent unit tests for `getBlobsV1` to cover all the scenarios we test in `getBlobsV2`. This would have caught the bug if I had added it earlier. It also caught another bug which could trigger duplicate block import.
Thanks Santito for reporting this! 🙏
