User data dir not passed to extension host debugee vscode window

[isidorn]

1. Get the hello world vscode extension
2. Start vscode with a new --user-data-dir
3. Try to debug the extension, notice that the new vscode window is opened, however the --user-data-dir is not passed to the new window. This results in the extension host not starting properly which shows up after some time.
