vcs-settings: moved creation of largefiles default dirs into vcs settings view.

- couldn't find a better place to do this
- check is cheap, and moving it out from AppStart to here makes more sense
- users need to enable largefile form this view, so enforcing defaults dirs
makes most sense right here in this view.
