[TIMOB-823] table view rows with height auto don't render properly (intermittently)

   var win = Ti.UI.createWindow({
       backgroundColor: '#fff'
   });
   
   var rows = [];
   
   for (var i = 0; i < 100; i++) {
       var row = Ti.UI.createTableViewRow({
           height: Ti.UI.SIZE,
           layout: 'vertical'
       });
       var rand = Math.random() * 5;
       var j = 0;
       while (j < rand) {
           row.add(Ti.UI.createLabel({
               text: 'Row ' + i + ', Label ' + (j++), textAlign: 'center',
               color: '#000',
               height: Ti.UI.SIZE
           }));
       }
       rows.push(row);
   }
   
   win.add(Ti.UI.createTableView({
       data: rows
   }));
   
   win.open();
