Rob Mulholand 82fd73ba3f (VDB-68) Verify log block hash matches header block hash
- Delete header on conflict to prompt data refresh (cascade deletes all
  data associated with that block)
- Derive header hash from rpc payload rather than computing it from data
  (prevents hash mismatch between blockchain and cache)
