[FIX] sale: taxes on report

- Create a tax using the tax template 'GST + QST for sales'
- Create a SO with the following lines:
  Product 1 100 Units @ 0.1
  Product 2 2000 Units @ 10.334
  Product 3 2000 Units @ 10.334
  Product 4 5000 Units @ 0.1
  Product 5 1500 Units @ 0.1
- The totals are:
  Amount without taxes: 41996.00
  Taxes: 6288.90

When printed, the quotation gives:
  Amount without taxes: 41996.00
  Taxes: 6286.52

This is due to the method `_get_tax_amount_by_group`, which is using
`line.price_reduce` for tax computation. Since it is a Monetary field,
it is automatically rounded to the currency precision, while it should
be rounded with the same precision as `price_unit`.
