[horde] H6 CardDav synchronisation with multiple email addresses

[Horst B Simon]

Hi,

I have enabled home and work email in Turbo backends.local.php, by removing the comments for
        'homeEmail' => 'object_homeemail',
        'workEmail' => 'object_workemail',

It  displays correct and synchronises correct if I use only one email address in the email field or use 
email addresses in all 3 email fields (email, homeemail and workemail), but if I use an email address in the homeemail or
workemail field, the synchronization will fill all fields, when I make a change on the client and sometimes it will place
two email adresses in one field. I can’t see a pattern in this behaviour. 

This works correct with Baikal as a CardDav Server and Roundcubemail, from which I want to migrate to Horde.

Best Regards,
Horst Simon
