Fix unexpected errors with deactivated accounts and managed group membership

[amstilp]

• Update the ManagedGroupMembershipAudit to consider account status when checking membership. It now does not show audit errors for a deactivated account when the record of a group membership exists in the app but not on AnVIL, and does show audit errors if the deactivated account is in the group on AnVIL.
