[FIX] account: fix bank statement import from BNP

Before this commit, importing an .OFX file from BNP failed because the account number format is not the same.

This is a problem on BNP's side but it is blocking for our clients and needs to be fixed.

This commit fixes this by checking that the account number corresponds to a specific part of the IBAN (for France only).
