Expected behavior

• Blocks with height height: undefined should not be scheduled for indexing
• Missing blocks job should be checking for missing blocks in the range contained within indexVerifiedHeight and latestBlockHeight

Steps to reproduce

• Run Lisk Service against testnet
  • First try running against the devnet
  • This probably pops up after the initial indexing catches up and the new.block signal kicks in

Which version(s) does this affect? (Environment, OS, etc...)
