[FIX] account_voucher: round globally

- Enable multi-currency. Company currency = USD, another currency = SGD
- Update the exchange rate
- Create a purchase journal. Assign SGD to this journal
- Create a purchase tax of 7.00 %
- Enable tax rounding globally
- Create a purchase receipt with the following values
  62.04 @ 7% tax
  7.29 @ 7% tax

An error occurs: 'Cannot create unbalanced journal entry.'

Each line of the receipt creates its own tax line, which is therefore
rounded => the total of the receipt is computed with a 'round globally'
configuration, while the taxes are computed with a 'round per line'
configuration.

This is because `apply_taxes=True` is set in the context. This creates
the tax line by forcing the rounding. Therefore, we call the method
`_apply_taxes` explicitly in this specific case, and manually round the
taxes once they are merged.
