[FIX] l10n_gcc_invoice: translate payment terms' notes correctly

## Steps to reproduce
- install l10n_gcc_invoice module
- switch to a company in Saudi Arabia (SA company)
- create and print an invoice that has a payment term with a translated
  note

We expect the payment term's note to be displayed both in English and
Arabic. But instead, the note is displayed twice in the customer's
preferred language.

## Cause
`t-field` does not use the context defined on the field itself. It uses
the rendering context.
