	** Fix for bug #325730

	* gui/e-memos.c: (table_selection_change_cb):
	* gui/e-tasks.c: (table_selection_change_cb):
	Clear task/memo preview when have more or less than one row selected.
	* gui/e-cal-model.c: (e_cal_view_objects_added_cb),
	(e_cal_view_objects_removed_cb), (remove_client_objects):
	First delete, then notify, so we read from updated store.
