If an element has a directive whose content is loaded using `templateUrl`, and the element is cloned using a linking function before the template arrives, the clone needs to be updated as well. This also updates `ngIf` and `ngRepeat` to keep the connection to the clone of a tranclude function, so that they know about the changes a directive with `templateUrl` does to the element in the future. Fixes to #4930.
