[TI-41] reports.week.hours=auto should ignore exclusions

Exclusions don't play nice with `reports.week.hours=auto`. In my configuration file I have defined:

```
exclusions.monday = <8:00 >22:00
exclusions.tuesday = <8:00 >22:00
exclusions.wednesday = <8:00 >22:00
exclusions.thursday = <8:00 >22:00
exclusions.friday = <8:00 >22:00
exclusions.saturday = >0:00
exclusions.sunday = >0:00
```
Now even if I use `reports.week.hours=auto` in my configuration file I still get hours displayed from 0 to 23. I think exclusions should be ignored in this case - they are not tasks that should be displayed.
