node: Neo CLI requires tty to start

[aprasolova]

It's impossible to start neo-cli with command dotnet neo-cli.dll /rpc if this process wouldn't have a tty allocated. The only way to run neo-cli with no terminal attached (in case if I'd like to run it in a docker container, for instance) is smth like screen -DmS node dotnet neo-cli.dll /rpc, i.e. allocate tty anyway.

I wonder, is it really necessary? If it's not, would you be so kind to get rid of this minor, but annoying defect?
