[FIX] hr_payroll_account: Allow salary rules to be used in multicompanies

Before this commit
- Install a **l10n_xx_hr_payroll** which includes information of the rules (it always install in the main company: **Company A** in this use case).
- Configure the accounting for the rules
- Create **Company B**
- Use the same salary rules for both companies, as **l10n_xx_hr_payroll** modules are not multicompany.

Behavior:
- **Company A** accounts are shown in **Company B** salary rules.
- If the accounts are changed in **Company B** rules, it also overrides **Company A** accounts, (which causes major confusions, and great mistakes if a payslip is run).
- A salary rule with **Company A** set on `company_id` can still be **seen** through Company B. which causes that it can be mistakenly _ran by a user in Company B_, with the _accounting of Company A_.

After this commit:
Salary rules accounting can be used with multi-company
