sfctl store delete does not work with local clusters

[esbenbach]

I am desperately trying to work around the issue that we are stuck on Windows Powershell to manage remote and local clusters.

For the most part sfctl "works" (with some issues), but sfctl store delete does not accept an image store connection string like "sfctl application upload" so we are unable to remove applications locally.

It seems like removing the application manually from the local file path works, but it seems wrong to go around sf like that.
