Step 2: Part 3 - test does not account for header row

[joargp]

The tests for ProductRows failed when we added a header row based on the UI-template given with "Name" and "Price" in the top.

We thought this was a ProductRow in the top, so we initialized the result array with a ProductRow.

var result = [
    ProductRow({name:"Name", price:"Price"}) 
];

This is due to the test expecting the same amount of ProductRows as there is products.

Maybe add a Header row as well?
