YN-0773: make sure variables are expanded in roots

[ynbot]

Please describe the feature you have in mind and explain what the current shortcomings are?

Make sure we expand variables in roots. So the root definition like this

 

{
"work": {
    "windows": "~/foo/bar"
}
}

 

will be properly expanded to for example /home/user/foo/bar
