SACs are not readers of anon AC groups

[carlosmondra]

SACs are not readers of anonymous AC groups. This is odd as they can see the identities of the ACs with the proposed assignment edges from the SAC console. Example:

{
    "id": "ICLR.cc/2022/Conference/Paper1/Area_Chair_vwjZ",
    "cdate": 1633669604162,
    "ddate": null,
    "tcdate": 1633669604162,
    "tmdate": 1635461087727,
    "tddate": null,
    "web": null,
    "signatures": [
      "OpenReview.net"
    ],
    "signatories": [
      "ICLR.cc/2022/Conference",
      "ICLR.cc/2022/Conference/Paper1/Area_Chair_vwjZ"
    ],
    "readers": [
      "ICLR.cc/2022/Conference",
      "ICLR.cc/2022/Conference/Program_Chairs",
      "ICLR.cc/2022/Conference/Paper1/Area_Chair_vwjZ" // Senior Area Chair is not reader: "ICLR.cc/2022/Conference/Paper1/Senior_Area_Chairs"
    ],
    "nonreaders": [
      "ICLR.cc/2022/Conference/Paper1/Authors"
    ],
    "writers": [

    ],
    "members": [

  }
