Original PR description

Save "without_demo=False" inside the configuration file, Odoo starts with demo data. Do the same but in the CLI "--without-demo=False" and Odoo starts without, this is a bug.

All strings "False" and "false" in the configuration file are automatically converted to the boolean False. The same doesn't apply with the CLI, so it was evaluating `not "False"` which is False.

Change the logic so that "False" and "false" are considered falsy.

Original PR description

Steps:
	- Install hr_timesheet_attendance.
	- Set the timezone (for both user and calendar) to Europe/Zurich.
	- Create Attendance records: [03/01/2025: 00:25:36, 03/01/2025: 10:25:59]
	- Create a Timesheet for 03/01/2025.
	- Open the Timesheet Attendance Report and group by day.
	- Check Attendance Hours and Timesheet Hours: Attendance Hours : Timesheet Hours
		02/01/2025:	10	     :       00
	        03/01/2025:	00           :       08

Issue:
	Attendance was shown as one day earlier than expected.

Reason:
	The check_in date was incorrect because it was using UTC instead of the employee's local time zone.
Fix:
	Converted check_in to the employee's local time zone before extracting the date.
