Fix add extra empty screen logic

The bug occurred when there are two widgets in a CellLayout. When
dragging one of the widget, ShortcutAndWidgetContainer#getChildCount
returns 1 rather than 2 because the LauncherAppWidgetHostView of the
widget in drag has been detached from its parent and reattached to
DragView (introduced in ag/14234627).

Test: Place only two widgets on the last page of the home screen. Drag
      one widget. The new page indicator on the right is shown.
