[FIX] sale_timesheet: project template

- Create 2 companies A & B
- Set the superuser in A
- Create a product P:
  Product Type: 'Service'
  Service Tracking: 'Create a task in a new project'
  Project Template: set one for both companies
- Switch to company B
- Create a SO with P, validate
- Access the project through the stat button 'Project(s) Overview'

An `AccessError` is raised.

In case no 'Project Template' has been set for company A, the project is
created without the specified template.

This is because the new project is created as `sudo`, and the
`project_template_id` field is a company-dependant field. Therefore, a
project template from company A is used to create a project in company
B.
