List view of events is really broken

One-sentence description

The list view doesnt work when birthdays are shown The list view shows too many events and events that already passed or are not in the timeslot

Current behaviour / Reproducing the bug

1. Click agenda (you see the calender view with a few events on it)
2. Click show verjaardagen
3. Click list
4. There is nothing on most weeks, or sometimes only 1 event from that week
5. KAPUT

1. Click agenda
2. Click show verjaardagen
3. Click list
4. Nothing (like case 1)
5. Click 'week' or 'maand'
6. Click toon verjaardagen
7. All verjaardagen are now dubbel (also kind of an issue but im too lazy to make a seperate thingy)
8. Click hide verjaardagen
9. Click list
10. Look at the date it says on top and the dates of the events in the list
11. Those events are not in the selected week
12. KAPUT

Expected behaviour

I want to see the events normally in a list
