Currently miner_std either tries to mine from ALL nodes or only the 0th node in the network. Since it also naively calls rpc createwallet and some older node versions do not support that command, the scenario fails. I think we can also modify the scenario to be more flexible with older versions but it also makes sense to be able to just pick a single mining node. The signet miner scenario already has this option.
