Default rpcurl doesn't construct Rpc object

[mradkov]

The server's default rpcurl is http://127.0.0.1:8941, meaning "connect to an existing node" is the intended primary mode, and --rpcurl=spawn is the special case. But the else branch never constructs the Bitcoin.Rpc object, so the server starts successfully and silently, then crashes on the first request.

	if (rpcurl === 'spawn') {
	localnet = await Server.regtestSetup({ debug });
	} else {
	debug(`Using chain ${rpcurl}`);
	}
