[FIX] sale_timesheet: Sales user not allowed to create invoice linked to timesheets

Steps to reproduce:
- Create a service product P with invoicing policy = Timesheets on tasks,
Service Tracking = Create a task in a new project and Re-Invoice Policy = No.
- Create a SO with P and confirm it
- Go to the task created for the SO and assign an employee on it.
- Valide the related analytic line in the timesheet module
- Create a user U with the following rights: Sales: 'User: all documents',
Project: 'Manager' and no right in Employee.
- Log as U and try to invoice the SO

Bug:

An access rights error was raised
