fix(ui): 🎨 fixup start & enable flag logic

refs #313

- the `ghost setup --start` flag
  - The default value for "start" is "prompt"
  - The fallback default value for "start", if it's not allowed to prompt is true
  - Passing --no-start will set start to false, and not prompt
  - Passing --start will set start to true, and not prompt

- the `ghost start --enable` flag
  - Enabling doesn't trigger any prompt
  - The default value for "enable" is true
  - Passing --enable doesn't change anything
  - Passing --no-enable prevents enabling

- calling `ghost uninstall` will now call `ghost stop --disable`
