Division by zero
Hello,
I'm using Cospend 0.0.9 on Nextcloud 15.0.2.
It was working smoothly, but after I changed the weight of a member to 0 - the member with the name Z - everything broke apart.
Now, when I open Cospend I get the error message Failed to get projects with the following log in Nextcloud:

Though the logs show that the error is on this line I think it's because it accepted a zero-weight on the first place.
I can create new projects and add members and bills, but when I refresh the page everything disappears and I got the same message Failed to get projects.
