Workaround CanJS/Mustache binding issue

* `instance.directive` is null when the modal is initially rendered for
  Section or Control creation.  It is then set to the appropriate value,
  but the element is not correctly rerendered if the reference is only
  `directive` instead of `instance.directive`.
Fix owner binding in Info widget

* Same issue as `directive` binding in Control and Section modals
