Auto calculate taxes and totals

Thanks for this plugin. I found that taxes and totals were not calculated until you opened the order and did ‘recalculate’. This meant that the initial email sent out could have zero taxes and totals and there could be confusion if you don’t ‘recalculate’ new order. This can be fixed by adding
$order->calculate_totals();
just before
$order->update_status('on-hold');
in class-clone-order, around line 142. It may also be required in bulk clone.
