[FIX] hr_attendance: set default filter for reporting

If you have a lot of attendance spread accross various employees and various dates,
the report takes ages to load (or your browser freezes and you can't access reporting).

And if it loads, the report is unreadable anyway. Use a default filter to always
display user friendly graphs. Since we group by day, a default period of a month seems
like a good compromise.

To reproduce the issue:
- install hr_attendance
- use a script to create some attendances (ex: create 300 employees and 30
attendance for each, spread randomly in the last 3 years)
- click on "Reporting"
