[BUG] in sample: quickstarts/taskqueues-backup-images/functions/index.js

### Which sample has a bug?
quickstarts/taskqueues-backup-images/functions/index.js

I have created my own queue with minor modifications provided in the **Failing Function code used** section. If someone can please help resolve the issue, I would really appreciate it.

**Sample name or URL where you found the bug**
quickstarts/taskqueues-backup-images/functions/index.js

### How to reproduce the issue
- create an index.ts file for functions with the below-mentioend code.
- Deploy `executeOrders` function to create the queue with the same name.
- execute `submitOrder` function.
- `enqueue` fails with message: `Unhandled error FirebaseFunctionsError: Queue does not exist.`

**Failing Function code used (if you modified the sample)**
```
import * as functions from "firebase-functions";
import * as firebaseAdmin from "firebase-admin";
import * as firebaseFunctions from "firebase-admin/functions";
import * as serviceAccount from "../serviceAccount.json";

firebaseAdmin.initializeApp({
credential: firebaseAdmin.credential.cert({
projectId: serviceAccount.project_id,
clientEmail: serviceAccount.client_email,
privateKey: serviceAccount.private_key,
}),
});

export const executeOrders = functions.region(
region,
).tasks.taskQueue({
retryConfig: {
maxAttempts: 2,
minBackoffSeconds: 10,
},
rateLimits: {
maxConcurrentDispatches: 1,
},
}).onDispatch(async (data) => {
functions.logger.info(data);
});

export const submitOrder = functions.region(
region,
).https.onCall(async (data, context) => {
const queue = firebaseFunctions.getFunctions().taskQueue("executeOrders");

functions.logger.info(data);

await queue.enqueue({"orderId": 1});
});
```

I also have tried to pass in the app object returned from `firebaseAdmin.initializeApp` to `firebaseFunctions.getFunctions()` as below, but still the same behavior.
```
const firebaseAdminApp = firebaseAdmin.initializeApp({
credential: firebaseAdmin.credential.cert({
projectId: serviceAccount.project_id,
clientEmail: serviceAccount.client_email,
privateKey: serviceAccount.private_key,
}),
});

export const submitOrder = functions.region(
region,
).https.onCall(async (data, context) => {
const queue = firebaseFunctions.getFunctions(firebaseAdminApp).taskQueue("executeOrders");

functions.logger.info(data);

await queue.enqueue({"orderId": 1});
});
```

**Steps to set up and reproduce**
- Env: node@16
- Typescript
- Deploy queue `executeOrders`
- Start function emulator or without emulator (I have tried both ways but I get the same behavior.)
- From any client call `submitOrder` function to enqueue a task in the `executeOrders` queue.
- Function throws an error when enqueuing the task: `Unhandled error FirebaseFunctionsError: Queue does not exist.` even when the queue exists.

### Debug output

```

**Screenshots**

### Expected behavior

The task should be enqueued under `executeOrders` queue.

### Actual behavior

Error message: `Unhandled error FirebaseFunctionsError: Queue does not exist.` even when the queue `executeOrders` exists.
