[17.0,18.0] accoun_loan: unable to post leasing with residual amount

[petrus-v]

Module

account_loan from version 17.0

Describe the bug

unable to post leasing with residual amount

To Reproduce

Affected versions: 17.0+

Steps to reproduce the behavior:

1. create a leasing (account.loan with is_leasing = True) fill leasing data as usual
2. add residual amount on leasing tab
3. generate lines
4. click post to open the wizard to choose the journal and click run
   currently I got the message

The total principal amount does not match the loan amount.

Expected behavior
We shouldn't be lock at this stage

Additional context

First investigation I guess this control should be aware of the residual amount https://github.com/OCA/account-financial-tools/blob/17.0/account_loan/wizards/account_loan_post.py#L92-L101
