When checking whether to use Roaming appdata(like on older installs or on installs where people deliberately use Roaming appdata) also check whether clients.config exists and if it does, set home to Roaming appdata since people may be updating from routers before the migration to clients.config.d directories. This should fix #16

[zzz]

The new lines should be inside an else {} as it's only needed if the check for clients.config.d fails.
