Issue Summary

When sending JSON details data from Opsgenie to JSM and setting the details into a text field it will be parsed as an object instead of a JSON.

Steps to Reproduce

1. Create an integration where an alert opens new Incident ticket in JSM
2. Send a JSON object as "Details" into the alert.
3. Populate a text field in the JSM ticket with the "Details"

Example payload:

{
    "message":"API Test",
    "details":
    {
        "snap_url": "https://p.datadoghq.com/snapshot/view/dd-snapshots-prod/org_2305/2014-07-23/examplepng",
            "group": "guruop",
            "name": "aws.dynamodb.returned_item_count",
            "type": "metric alert",
            "group_key": "key5",
            "query":"min(last_5m):avg:system.cpu.idle{*} < 99",
            "message": "@opsgenie-service_1",
            "org_id": 2305,
            "id": 59482,
            "metric": "system.cpu.idle"

    }
}

Expected Results

The JSM Ticket should present the following data:
