To reproduce, import and invoice containing one line with a tax of
i.e. `21%` on it.
Because the message is recursively expanded to follow the relation of
the field, the interpolation symbol needs to be escaped every time.
Otherwise the message will contain something like
> No matching record found for name '21%' in field '%(field)s/Taxes'
Where `'21%'` will try to be mistakenly interpolated.
