[BUG] Blank Screen in edge case

[MalteMagnussen]

When you don't select a date (leave it on default) then quickly select "see events" you get a blank screen.
(Doesn't occur 100% of the time, but easily reproducible for me.)

To Reproduce
Steps to reproduce the behavior:

1. Go to https://semholdkrykke.surge.sh/#/
2. Click on a country
3. Click on a city
4. Quickly click on "See events"
5. See blank screen

Screenshots

Console shows a lot of errors.

I think I know what the issue is. (Errorhandling does not handle react errors properly)

edit:
I'll give it a look
