[sync] Trouble keeping SyncML in sync with IMAP store

This is definitely not the correct way. The history entries have to be  
created directly in the drivers. In some cases this already happens  
either outside the drivers or in the driver parent class. Where this  
is not the case, it has to happen in the Kolab drivers, just like we  
do in the other drivers already.
