[FIX] hr_timesheet_attendance: fix the timesheet attendance report

Attendance report is calculated from the timesheets of all the companies
when multi-company is enabled but only one company is allowed. This commit fixes it.

Steps to reproduce:
 - Create two companies
 - Create an employee with a user allowed in both companies
 - Create timesheets in both companies for that employee
 - Allow only one of the two companies
 - Check the Timesheet Attendance report -> timesheets from both companies are counted
