fix: Wrap partial cache entry in CacheEntry

Because it is returned here: https://github.com/nextcloud/server/blob/7b7d07c5750583ab3a7b29112af475f5c8891143/lib/private/Files/Cache/Cache.php#L136-L137

And some implementation got stricter: https://github.com/nextcloud/groupfolders/blob/df95bf6ba807da5171de91108879b6d8aa9f3611/lib/Mount/RootEntryCache.php#L23-L28
