If rebinding, bind any existing views in @iterated

Prior to this change, an each-* bound view could be rebound but only at
the array level.  i.e.: any existing views that had been realized
weren’t being bound again.  This let you realize changes to the array
itself, but changes to existing elements of the array were not being
reflected into the DOM.
