invoices with escompte using account_fr
As indicated by the French National Accounting Authority in their document "REGLEMENT ANC N° 2014-03 RELATIF AU PLAN COMPTABLE GENERAL VERSION CONSOLIDEE AU 1ER JANVIER 2016",
the 'expense' account '665 Escomptes accordés' is valid on client invoices and by consequence the 'revenue' account '765 Escomptes obtenus' is valid on supplier invoices.
Currently, importing invoices using these accounts fail in the domain validation.
Either account_fr.xml needs to inverse the kind of these two accounts accordingly, or some special treatment needs to be put in place.
