[Tizen] Fixed an incorrect ellipsis

ex)
1. An ellipsis may be displayed incorrectly when there are two or more new-line characters.
2. The ellipsis location is incorrectly displayed for RTL text.

    TextLabel textLabel1 = TextLabel::New(  "abcdef הגדרות מהירות ");
    textLabel1.SetSize( 150.f, 100.f );
    textLabel1.SetProperty( TextLabel::Property::POINT_SIZE, 20.f );
    textLabel1.SetProperty( TextLabel::Property::ELLIPSIS, true );
    textLabel1.SetPosition( 100.f, 50.f );
    textLabel1.SetParentOrigin( ParentOrigin::TOP_LEFT );
    textLabel1.SetAnchorPoint( AnchorPoint::TOP_LEFT );
    stage.Add( textLabel1 );

    TextLabel textLabel2 = TextLabel::New(  "הגדרות מהירות");
    textLabel2.SetSize( 150.f, 100.f );
    textLabel2.SetProperty( TextLabel::Property::POINT_SIZE, 20.f );
    textLabel2.SetProperty( TextLabel::Property::ELLIPSIS, true );
    textLabel2.SetPosition( 100.f, 125.f );
    textLabel2.SetParentOrigin( ParentOrigin::TOP_LEFT );
    textLabel2.SetAnchorPoint( AnchorPoint::TOP_LEFT );
    stage.Add( textLabel2 );

    TextLabel labe21 = TextLabel::New(  "yesterday all my troubles seemed so far away now it looks as though they`re here to stay oh i believe in yesterday" );
    labe21.SetSize( 450, 145 );
    labe21.SetParentOrigin(ParentOrigin::TOP_LEFT);
    labe21.SetAnchorPoint(AnchorPoint::TOP_LEFT);
    labe21.SetPosition( 100.f, 200.f);
    labe21.SetProperty(TextLabel::Property::POINT_SIZE, 17.6f);
    labe21.SetProperty(TextLabel::Property::ELLIPSIS, true);
    stage.Add( labe21 );

    TextLabel labe33 = TextLabel::New(  "yesterday all my troubles seemed so far away\nnow it looks\n as though they`re here to stay\n\n ohi believe in yesterday" );
    labe33.SetSize( 450, 145 );
    labe33.SetParentOrigin(ParentOrigin::TOP_LEFT);
    labe33.SetAnchorPoint(AnchorPoint::TOP_LEFT);
    labe33.SetPosition( 100.f, 250.f);
    labe33.SetProperty(TextLabel::Property::POINT_SIZE, 17.6f);
    labe33.SetProperty( TextLabel::Property::MULTI_LINE, true );
    labe33.SetProperty(TextLabel::Property::ELLIPSIS, true);
    stage.Add( labe33 );

    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, 400.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 );
