[FIX] hr_expense: post expense paid by company

It is not possible to post the journal entries related to an expense
paid by the company

Steps to reproduce:
1. Install Expense
2. Create an expense payable to company
3. Set an amount
4. Create report
5. Submit report
6. Approve report
7. Attempt to post
8. An error is thrown

Solution:
Relax the constraint on account.move.line linked to an expense paid by
the company

Problem:
The constraint `_check_payable_receivable` in the account module forbids
to post the journal entries even though they are correct
