Refactor task payload extraction and update workflow builder

Browse source 
Modified the way task payload is extracted in the OrderFoodTaskHandler.cs for more robustness. The input parameter of the workflow builder in the HungryWorkflow.cs file has also been refactored for efficiency. Making these tweaks streamlines management of values within the tasks.
