bitcoind: importmulti fails (bitcoin master), use importdescriptors

Browse Source 
But this requires a watch-only wallet, and python-bitcoinlib doesn't support
multiple wallets, so we need to unload the original one, but then we need
to generate a block, so that can't generate a new address, so we need
an address arg to generate_block.
