Resolve "TypeError: Cannot read properties of null (reading 'id') on configuration search page"
requested to merge 457-fix-type-error-read-roperties-of-null-reading-id-con-configuration-search-page into develop
Closes #457 (closed)
This in fact fixes an issue with some old configurations on our GFZ instances - those that have no permission group for the configuration yet.
In fact, there should be no new value that triggers this kind of problem. But in order to avoid problems with our existing data, I make the changes here to make it more robust (and as we still cover the case for internal configs without permission groups in the canModifyEntity (store/permissions.ts), it seems valid to me to make this fix).
