not-existent JSON --genesis-json = throw: open_chain_database(), json lib, readsome()

If the --genesis-json file does not exist, then we should tell user in nicer way, the exception and last logs make it look more like the state database, and not reading the genesis file provided.

In commit 6129305f544819949399aefe5359bd4925cff138 (HEAD -> dbg_slots_fork, origin/dbg_slots_fork) based on upstream 597e70efb868ff6d44a0734627c4b9d0eb07aeea

• This should be an error that is more user friendly.
