Cloud storage: try to work around weird Windows rename issue

In some cases the rename of the cache directory would fail in my testing.
Based on code that Lubomir provided, this tries a Windows specific
implementation of folder rename if the QDir based one fails for some
reason - but obviously only if we are running on Windows.
