Contact groups/categories not shown in OS X Address Book after vCard import

[sushidave]

Scenario

Migrating contacts from an external ownCloud provider to own server with ownCloud/Nextcloud.

Steps to reproduce

1. OS X Address Book with some addresses with groups, stored on an ownCloud server of a provider. As expected, the groups are listed in the Address Book.
2. Export vCard file in the Address Book
3. Deactivate CardDAV account
4. On an own Nextcloud 9.0.53 server: Import the vCard file via the Contacts app.
5. OS X: Set up and activate CardDAV account for this server.
6. OS X Address Book: Check if groups are listed.

...or...

1. • 3. see above
2. OS X: Activate CardDAV account for the Nextcloud server.
3. OS X Address Book: Import the vCard file.
4. OS X Address Book: Check if groups are listed.

Expected behaviour

• OS X Address Book shows the list of groups of the contacts on Nextcloud.

Actual behaviour

• OS X Address Book doesn't list any groups. All contacts appear in "All Contacts" only. However, in the Contacts app of the Nextcloud user interface the groups are shown as expected.
• Same behaviour noticed with the own server before migrating it from ownCloud 9.0.3 to Nextcloud 9.0.53.
