Merge #21053: rpc, test: document {previous,next}blockhash as optional
ba7e17e073f833eccd4c7c111ae9058c3f123371 rpc, test: document {previous,next}blockhash as optional (Sebastian Falbesoner)
Pull request description:
This PR updates the result help of the following RPCs w.r.t. the `previousblockhash` and `nextblockhash` fields:
- getblockheader
- getblock
Also adds trivial tests on genesis block (should not contain "previousblockhash") and best block (should not contain "nextblockhash").
Top commit has no ACKs.
