title: re-open vscode without last workspace or last files
body: <p>I wish set <code>VSCode</code> to be launched clean, no last workspace or last files opened..
  is this possible?</p>
  
  <p>I use it as unity3d debugger and annoying me all the times that opens a previous workspace (no workspaces saved)</p>
  
  <p>thanks in advance</p>
