Integrate the function that saves current games array to the home page

[davidzherd]

Create integration for the new function. AC:

1. The homepage should first check if there is a saved games array - if there is such an array, then use it as the current games array.
2. If there isn't a saved games array - run the data function to create a new games array.
3. Update the data function to call the save to session storage function when fetch is complete.
