When asking for sharees we compare not only UID and displayname but also the email address. And if that matches we return the sharee as an exact match. This logic had a flaw as in that it also matched the empty string to users with no email address. This is most noticeable when you disable sharee enumeration and open the ownership transfer dialog. It suggested other users of the instance before. This has stopped now. Signed-off-by: Christoph Wurst <christoph@winzerhof-wurst.at>
