Contacts with only ORG get a wrong first/last name on sync

[rfc2822]

Steps to reproduce:

1. Set up a DAVx5 address book, sync
2. Add a contact with only an organization ("Only A Company") and a phone number.
3. Contact is exported as

FN:Only A Company
ORG:Only A Company

because vCard always requires a FN.

4. Unselect address book, sync, select address book again, sync again.
5. Contact is downloaded and imported into Android. vcard4android generates an Organization data row (content: "Only A Company") and also a structured name data row (containing only a display name: "Only A Company").
6. Because the structured name data row is created without components, Android splits the display name into components.

Result:

If the downloaded contact is opened in a contacts app, it shows the correct organization but also First name: Only, Middle name: A, Last name: Company.

Expected result:

Contacts app should only contain the organization, without first/last name.
