[FIX] hr_payroll_account: analytic account

- Set an analytic account on an employee contract
- Set credit and debit accounts on the salary rules
- Create a payslip, confirm

The journal items created do not use the analytic account set on the
contract.

If no analytic account is set on the salary rule, we fall back on the
contract account.
