We cannot add the notification insert id directly to the following contactnotifications queries. Instead we need to pass a DbValue reference which gets set after the notification insert id is calculated. The contactnotifications insert queries are fired as query group calling CanExecuteQuery() and FieldToEscapedString(). If the notification id does not exist yet, the queries are moved to the end of the queue. Once the contactnotifications queries are fired the DbValue reference is destroyed. This patch also removes the old notification insert id cache which was broken in many ways. fixes #11387
