Code review comment for lp:~laetitia-gangloff/account-invoicing/account_invoice_merge

About which MP should be the base to converge both in one, it seams Leatitia's MP is more advanced in the porting with details such as in views specifics to v7.0 and few more cleaning.

Furthermore, I agree with Stéphane, account-invoicing is certainly better than account-financial-tools branch

So let's keep this branch and bring what is needed from Romain's one?
