[FIX] sale_timesheet: propagate company

On Sales order confirmation, a project can be create. The project
company is not correctly propagated: the created project should
be in the same company as the SO.
To stay consistent, during the sold quantity conversion into the
planned hours of a task, we need to use the SO company instead of
the one of current user.
