babel-upgrade is broken if you have spaces in user folder.

[Xarkam]

Hello,
I have a space in my user folder name :

C:\Development\test\onsenui-vue-cordova-test > npx babel-upgrade
Error: EPERM: operation not permitted, mkdir 'C:\Users\xarkam'

The real folder is C:\Users\xarkam xarkam\

Thanks for fix it.
