Display all required contact data in token holders list

[MishkaRogachev]

The token holder list in SortableTokenHoldersList.qml can display two types of entries:

• Unknown token holder, who is not a community member. For such holders only wallet address is displayed.
• Community member token holder.

For second case we should add a contact details such as online status, ens, ringSpecModel and etc.

The way i see it is to reuse StatusSmartIdenticon and getContactDetailsAsJson:

    function updateContactDetails() {
        contactDetails = contactId !== "" ? Utils.getContactDetailsAsJson(contactId, false) : null
    }

    onContactIdChanged: root.updateContactDetails()

    Connections {
        target: root.store.contactsStore.myContactsModel

        function onItemChanged(pubKey) {
            if (pubKey === root.contactId)
                root.updateContactDetails()
        }
    }
