When syncing address book entry via CardDAV Horde is sending the  
CATEGORIES property with wrong separation. Horde internally uses  
categories as tags (or vice versa).

RFC is postulating for CATEGORIES property value: "One or more text  
values separated by a COMMA character"
https://tools.ietf.org/html/rfc6350#section-6.7.1

Horde separates by a comma and a space character.

This misbeavior is coming from function synchronizeTags(array $tags)  
in turba/lib/Object.php
...
$this->setValue('__tags', implode(', ', $tags));
...
https://github.com/horde/turba/blob/master/lib/Object.php#L313

Some CardDAV clients , for example Thunderbird plugin CardBook, adding  
the additional space char to the name of the category . As CardBook is  
using categories for grouping cards, this leads to lots of confusion.

Looking forward to seeing this fixed.
