Fixes #316

[Schrank]

Thanks @nige-one

Did you test this @Schrank? I just tested it and it does not change anything for me. The "Shipping & Handling Tax" is still shown separately and does not show any tax rate. Are you sure this works @nige-one?

[Schrank]

No, I just added it and then left the room :) (no joke)

It works like a charm for me. Just tested it again, dropped my XML totals extension from #316 (comment) and copied the new file from the PR.

Maybe a configuration issue. Here is mine:

Note the overridden fields, which do not seem to take affect, since everything is still working as expected in the B2C configuration.
This installation is version 1.9.3.6.

By the way: I changed

    public function __getCalculatedTaxes()
    {
        return array();
    }

to

    public function _getCalculatedTaxes()
    {
        return $this->_getTaxHelper()->getCalculatedTaxes($this->getSource());
    }

I really can't remember why at the moment, but I think it has something to do with rendering the order itself as PDF to use it as order confirmation. Probably this addresses #297 (comment) as well.

@nige-one could you provide a screenshot of the totals section of the invoice PDF? Mine looks like this:

As you can see, it still dows not show the tax rate of the shipping and handling tax.

[nige-one]

Ok, I have to extend my answer.
Shipping tax and value of goods taxes get only summed up if you return an empty array for both functions _getShippingTax() and _getCalculatedTaxes().
So @Schrank's PR should lead to the wanted behaviour.
