Ios app crashes when navigating through sitemap - sometimes

[joseibert]

New bug checklist

• I updated the iOS openHAB app to the latest TestFlight version. => V1 app?!?
• I read the Contribution Guidelines
• I searched for existing GitHub issues

Describe the bug
The app crashes at one time instantly and repeatable when opening a group on the sitemap.
If you wait some time (in my case 5 hours), everything works fine again.

To Reproduce
Steps to reproduce the behavior:

1. open the app (with the sitemap view)
2. Click on a group to open the detail page of that group
3. The detail page shows up for a second and then the app crashes.
4. This is reproducable with different group derwil pages also.

Expected behavior
App should show the group page without crashing.
