Switching between PowerShell versions on Windows is unreliable

[daviwil]

It appears that after the latest upgrade to vscode-languageserver we've lost the ability to switch between PowerShell versions cleanly using the status bar menu. Sometimes it hangs at startup causing the extension host to crash after a timeout. Other times it seems to work fine. There must be some initialization step that we need to clean up when using the newer version of that library.

For me the integrated console hangs when I run the "PowerShell: Restart Current Session" command. Not sure if that is related, or if it should be logged as an issue of its own.

I think it's the same issue, I'll look into it today.
