[KOE-108] Copying contacts out of the GAB failed as it triggers a write event that is rejected. Fixed by rejecting write events only if there are preceding property changes on the same item. Also fixed a bug that the rejection dialog box was sometimes not shown by setting the parent window explicitly.
