8.0 l10n ca account check writing

Attempt at porting l10n_ca_account_check_writing to v8.

res_currency_print_on_check is a dependency and needed
porting as well.
`voucher_line.amount_unreconciled and voucher_line.amount_unreconciled or False` can be shortened to `voucher_line.amount_unreconciled or False`
