[horde] Issue on fresh install with translation and carddav

That looks like your SabreDav installation is too new. Current horde
relies on some SabreDav interfaces which have been refactored/renamed on
newer SabreDav.

See https://wiki.horde.org/Doc/Dev/DAV/DeveloperNotes?version=1

I think you should be save with a SabreDav 2.x release.
