#20 Create function for "back to home" button

[YuriDevAT]

As a user, I want the possibility to delete the current list and go back to the home view, where I have the chance to create a new list or join an existing list.

AC:
When clicking the back to home button in the list view, a modal appears where I can choose to delete my actual list and be redirected to the home view
