Only other integration I can see that has dirmapping is Nuke, which uses just `dirmap` without host prefix - which I suppose would then be broken regardless.
It may make more sense to remove the `host` specific prefix from the label because it's already looking in host specific settings anyway.
Site Sync addon throws ValueError for no local/studio sites as it doesn't make sense to override roots for sftp or gdrive.
This handles gracefully this exception.
Addon's get_site_root_overrides should return overridden root values for any site which is overridden by Site Settings.
'studio' site is currently overridden by `Roots` tab and comes from project settings directly.
