Version 5.3 breaks how teams output is returned by the API

[mhxion]

This is likely happening due to teams no longer returning a valid JSON, but rather a pure string (where JSON syntax is escaped) and thus is not de-serialized to Python dictionary. Was this intentional?!

# 5.3:
  "teams": "[{\"id\": 51, \"name\": \"MedFaculty Demo\", \"is_admin\": 0, \"is_owner\": 0, \"is_archived\": 0}, {\"id\": 4, \"name\": \"FOO BAR\", \"is_admin\": 0, \"is_owner\": 0, \"is_archived\": 0}]",
  "team": 1
}

# Before:

  "teams": [
    {
      "id": 3,
      "name": "Foo",
      "usergroup": 4,
      "is_owner": 0
    }
  ]
}

The bill-teams, whoami will throw the following error:
