Share policy prevents fetching document from sync server

[cklokmose]

Requesting a document with repo.find from a peer (e.g., a sync server) will fail if the sharePolicy doesn't return true on the peer id.
The following code reproduces the error as the document here will never load.

import * as AutomergeWasm from "@automerge/automerge-wasm"
import * as Automerge from "@automerge/automerge"
import { Repo } from "@automerge/automerge-repo"
import { IndexedDBStorageAdapter } from "@automerge/automerge-repo-storage-indexeddb"
import { BrowserWebSocketClientAdapter } from "@automerge/automerge-repo-network-websocket"

async function initializeRepo() {
    console.log("Creating repo")
    const repo = new Repo({
        storage: new IndexedDBStorageAdapter(),
        network: [new BrowserWebSocketClientAdapter(`wss://sync.automerge.org`)],
        peerId: "client-" + Math.round(Math.random() * 1000000),
        sharePolicy: async (peerId) => false,
    })

    await AutomergeWasm.promise
    return repo
}

const repo = await initializeRepo()
let handle = repo.find(`automerge:4UJNqDEtH5Eit5cs4uo1inxpMtpW`)
await handle.whenReady();
let doc = await handle.doc();
console.log("doc", doc);
