    edit: Prevent a crash with duplicate recipe IDs
    
    When we fail to add a recipe to the store, don't set page->recipe,
    since that will lead us down the wrong path (calling update_recipe
    instead of add_recipe) if we try to save it again, causing us to run into an assertion in the recipe store
    code.
