Using custom media during redeployment when no media in deployment request

Steps:
---------
1. Deploy an order with custom media.
2. After successful deployment, remove the media or remove all the ads from the deployment request.

{
"merchantUuid": "8866c0e9-7441-4c3c-be96-7adf01a42df7",
"primaryDestinationUrl": "http://www.merchantsite.com",

"name": "quote Name",
"comments": "This is Comment section",
"campaignList": [

{ "baId": 10001, "locationId": 4189, "distribution": "FACEBOOK", "isPrimary": true }

],
"distributionBudgets": [

{ "monthlyBudget": 125, "distribution": "FACEBOOK" }

]
}

3. Redeploy the order without ad elements.
4. verify the media and ads.

Problem: During redeployment it should use system ads as there is no any ad elements in my deployment request. But its using previously customized ads during redeployment.
