Task: 2817024
1. l10n_cl uses _prepare_tax_lines_data_for_totals_from_invoice() and _get_tax_totals() to prepare invoice totals for exporting invoices in pdf.
After the recent changes these methods no longer exist and invoice totals should be calculated in a different way.
2. Contact widget should not have ```'no_tag_br': True``` anymore to show the address properly.
