Purge CardDAV addressbook
So with the latest Sailfish release ("Aurajoki" 2.0.2.48) I'm happy to report that CardDAV sync with Horde is finally working, and I can now start using my Jolla, which has been sitting in a drawer for over six months! But I've quickly run into another issue: I had way too many contacts in my address book, and to clean them up I created a second address book in Horde called "Archive" and moved those contacts I no longer need into it. This didn't stop the Jolla from keeping these contacts, at first I thought because it uses the "principal" URL for CardDAV and will find the "Archive" as well as my "Main" address book, but even after deleting the "Archive" from Horde and re-syncing multiple times the old contacts still appear in the "People" app on the Jolla. How can I get rid of them!?
