[FIX] point_of_sale: aml from pos.order.line should have their tax group and children

Having a product on which a group of taxes apply (containing children taxes, obviously)
Make a sale
Validate the entries

Before this commit, the account_move_line created from the pos.order.line
had only the group of taxes as their tax_ids
Which is inconsistent against what account.invoice do,
and against what the generic report tax does

After this commit, we imitate what happens on invoices, and the movel line
created from the pos.order.line has the children of the group and the group as tax_ids
