[Tizen] Fixed an incorrect ellipsis

ex) An ellipsis may be displayed incorrectly when there are two or more
new-line characters.

    TextLabel labe34 = TextLabel::New(  "yesterday all my troubles
seemed so\n\n\n\n far away now it looks" );
    labe34.SetSize( 450, 100 );
    labe34.SetParentOrigin(ParentOrigin::TOP_LEFT);
    labe34.SetAnchorPoint(AnchorPoint::TOP_LEFT);
    labe34.SetPosition( 100.f, 500.f);
    labe34.SetProperty(TextLabel::Property::POINT_SIZE, 17.6f);
    labe34.SetProperty( TextLabel::Property::MULTI_LINE, true );
    labe34.SetProperty(TextLabel::Property::ELLIPSIS, true);
    stage.Add( labe34 );
