Shopping List - Update

[alemputes]

As a User, I want to be able to update a shopping list.

Note: This is the view with the collection of the shopping lists, not the actual items.

• [x] Create button for update
• [x] Display dialog for updating
• [ ] If saved should update the API
• [x] Update the change in UI

Same here needs the API for update implementation then it's to be done.
