Steps to reproduce:Set up a Caldav calendar (mailbox.org here). With DAVx5 connect to this calendar. Cause an syncing error. In this case deleting a recurrent birthday reminder caused an error 403 (Forbidden) from the server.
Expected behaviour:DAVx5 continues with the next sync item, trying to sync as many items as possible. DAVx5 informs the user about all failed items.
DAVx5 stops the sync. Many other sync items are not synced because one single failure.
