Fix mount type root detection

Since Webdav doesn't contain that information, we need to rely on the
parent folder's mount type to find out whether a child item is a
shared/external root or not.

Fixed the mount type detection logic and added unit test.

Also added a fix that ignores detection if no parent folder exists (ex:
shared file list, favorites, etc)
