## Steps to reproduce:
- Install **Timesheets** and **payroll** apps.
- Create a copy of the (**Standard 40 hours/week**) working schedule but remove **Wednesday** working hours.
- Create a new **employee**, and set his Working Hours to the newly created working schedule.
- Create a new **_running_** **contract** for the newly created employee with the newly created working schedule.
- Go to **Timesheets** app, and search for the newly created employee.
- **Add a line** for a project and register 8 hours in each day from Monday to Saturday.
- Switch the view to Day, Notice how for both Wednesday and Saturday, no overtime is shown. +08:00 should be shown for each as both are non-working days per the newly created working schedule. **(Issue 2)**

## Investigation:
- The overtime text comes from https://github.com/odoo/enterprise/blob/1720b5578998b28c91c6820a63ecbd397297c47f/timesheet_grid/static/src/components/employee_overtime_indication/employee_overtime_indication.xml#L8 using `overtimeIndication()` getter https://github.com/odoo/enterprise/blob/1720b5578998b28c91c6820a63ecbd397297c47f/timesheet_grid/static/src/components/employee_overtime_indication/employee_overtime_indication.js#L34
- For the off days - (Wed, Sat, Sun) in our example -, the `allocated_hours` (`this.props.allocated_hours`) = ZERO
- And so `shouldShowHours()` returns `false` https://github.com/odoo/enterprise/blob/1720b5578998b28c91c6820a63ecbd397297c47f/timesheet_grid/static/src/components/employee_overtime_indication/employee_overtime_indication.js#L19-L21
- which makes `overtimeIndication()` returns null. That's why no overtime text is shown for off-days
- Note that `allocated_hours` is `undefined` for rows that represent employee hours of the current week
