Remove-Item failure on AppVeyor

[michaelmior]

The build and deploy still works, but I get this message near the end. I'm not familiar with Powershell so I'm not really sure what's going on.

Remove-Item : The method or operation is not implemented.

I encountered it after changing the layout of $STAGE's contents in a way I think caused the earlier Remove-Item *.* to match no files. I'm not clear on exactly which part failed but I changed

Remove-Item *.* -Force
Set-Location ..
Remove-Item $STAGE

to

Set-Location ..
Remove-Item $STAGE -Force -Recurse

to recursively delete $STAGE and that works.
