Some permission rules can cause re-sync after every reload of the app

[sleidig]

Describe the bug
On dev system the following rule causes the sync to re-start completely every time the app is reloaded or the user logs in anew.

To Reproduce
The following permission rule seems to cause the issue:

{
  "subject": "Child",
  "action": "manage",
  "conditions": {
    "assignedSchoolProject": {
      "$in": "${user.projects}"
    }
  }
}

--> demo.aam-digital.net with user demo (pass)
