[FIX] hr_timesheet: Analytic account without company

Steps to reproduce the bug:

- Let's consider a project P set with analytic account AA and company C
- Allow timesheet on P
- Let's consider a task T belonging to P
- Set AA with comapny = False
- Try to encode a timesheet on T

Bug:

A UserError was raised because the field company_id on account.analytic.line is required
