    Fix tree view if config contains " (#9250)
    
    If you run DAG with `{"\"": ""}` configuration tree view will be broken:
    ```
    tree:1 Uncaught SyntaxError: Unexpected string in JSON at position 806
        at JSON.parse (<anonymous>)
        at tree?dag_id=hightlight_test&num_runs=25:1190
    ```
    
    JSON.parse is given incorrectly escaped json string.
    
    (cherry-picked from a8cd23c8f04c29a3bc37e9a1aec2fbdf044116e4)
