Bug:
The email is not translated in the partner's language

Explanation:
The context of the template didn't take the current partner's language
into account since it was out of the partners loop.
The subject of the email wasn't aware of the partner's language as the
context hadn't been changed.

Wrapping the translations with the right `lang` context value fixes the
issue.

Also, the subject used the formatted string as the translation source.
This makes it impossible to find a matching translation since the source
is different every time.
