Crash when creating two contacts without name
Steps to reproduce
- Create 2 contacts where you don't enter a name
- Then you link the 2 created contacts or in German translation you click on "Verknüpfen"
A random number is now created
Then you edit this contact and will give it a name like "test" and try to save it
Now the contact app crashses
I have tried it in version 3.38.1 on Fedora 33
