Copy minSpanX & minSpanY when copying from an existing ItemInfo

Test: Drop Gmail widget to home screen and configure it. Then, drop
      the widget to a home screen that doesn't have sufficient space
      to accommodate it. The gmail widget can't be dropped to that
      home page and is returned to its original position.
