Pick the right attribute value for form.$name if ng-form directive is used as an attribute

[lastnico]

Pick the right attribute value for form.$name if ng-form directive is used as an attribute.

This is especially important when you want your inner form to be published as a control of its parent form.

Currently, if you have this code snippet:

<form name="mainForm">
  <div ng-form="subForm">
    ...
  </div>
</form>

-> mainForm.subForm will not be available

---

<form name="mainForm">
  <div ng-form="whateverValue" name="subForm">
    ...
  </div>
</form>

-> while it will work in this case.
