Adding a new contact sets the displayname to the current displayname, instead of leaving it empty so it can change when the contact changes their name

• Operating System (Linux/Mac/Windows/iOS/Android): xubuntu 22.04
• Delta Chat Version: 1.46.0
• Expected behavior: For contacts where I never set a display name manually, the display name changes when the contact changes it.
• Actual behavior: The display name they had when I met them stays, even if they change it, unless I explicitly remove it in the UI.
• Steps to reproduce the problem:
  • click on an invite link to add a contact, e.g. OPENPGP4FPR:AA5FDEF02BFC355FDEA09FF4CA4AFCD2F065E613#a=deltawoot%40nine.testrun.org&n=Friendly%20Chatwoot&i=q4DhTVr1T2A&s=mT3Bo9JDdVx
  • click on their name to display contact information
  • click edit in the top right to edit the display name
  • realize that it is not empty, but set to the current name
  • exit without changes
  • from the other profile, change the display name
  • from the other profile, send a message to yourself
  • realize the display name in the app is not changed
  • edit the display name to remove it
  • realize that now the display name is the changed one

I noticed this (names not empty) too, but I didn't know it was related to invite links
