setup dialog opens after tor restart when TOR_FORCE_NET_CONFIG=1

In the "new" Tor Launcher UI, the progress bar is integrated into the same window as the initial setup wizard. Unfortunately, I found a way to get the window to open in the wrong mode (setup instead of progress). Steps to reproduce:

1. Set TOR_FORCE_NET_CONFIG=1 in your environment.
2. Start Tor Browser and connect.
3. Allow bootstrapping to finish.
4. Kill the tor (tor.real on macOS) process.
5. Click Restart Tor when prompted inside Tor Browser.
