ghost uninstall --no-prompt causes error

[ErisDS]

This isn't an important use case for pre 1.0.0, just flagging up that this behaviour is a bit odd:

ghost uninstall --no-prompt
WARNING: Running this command will delete all of your themes, images, data, and any files related to this ghost instance!
There is no going back!
/usr/lib/node_modules/ghost-cli/node_modules/yargs/yargs.js:1079
      else throw err
           ^

Error: Prompts have been disabled, please provide options via command line flags
