PoW check despite using no-seal-check during import

[holiman]

See ethereum/hive#121

In hive, some tests does not have proper PoW. We implemented the relevant commands to skip PoW for Geth, Aleth and Parity. It's been tested to work with geth and aleth, but still does not quite do it for Parity, using the --no-seal-check option on the commandline:

[8fba75f2] Loading remaining individual blocks...
[8fba75f2] /parity  --no-discovery --no-seal-check --chain /chain.json import /blocks/0001.rlp

[8fba75f2] 2018-09-01 12:11:37 UTC Stage 1 block verification failed for 0x0e81…5afb: Error(Block(InvalidProofOfWork(OutOfBounds { min: Some(0x20000), max: None, found: 0x2 })), State { next_error: None, backtrace: InternalBacktrace { backtrace: None } })
[8fba75f2] Cannot import block: BlockImportError(Block(InvalidProofOfWork(OutOfBounds { min: Some(0x20000), max: None, found: 0x2 })), State { next_error: None, backtrace: InternalBacktrace { backtrace: None } })

I thought that was the correction usage -- but any pointers on how to do it is appreciated.

Do you mind sharing your chain.json and the block rlp? Should be fixed in #9470 but haven't tested.
