Merge #16325: rpc: Clarify that block count means height excl genesis

fab0c820fa4c0c3227eec85c64310a3bf938a149 rpc: Clarify that block count means height excl genesis (MarcoFalke)

Pull request description:

  There is a common misconception that the block count returned by the blockchain rpcs includes the genesis block. See for example the discussion in https://github.com/bitcoin/bitcoin/pull/16292#issuecomment-506303256.

  However, it really returns the height, which is `0` for the genesis block.

  So clarify that and also remove the misleading "longest blockchain" comment.

  Finally, fix the wallet test that incorrectly used this rpc.
