    placeButtons: Fix bug when adding favorites
    
    When you searched for a place in your Recents list, then added it to your
    Favorites through the PlaceBar, it would lose all its Overpass information.
    Fixed by always using the PlaceStore version of a place in PlaceButtons.
    
    See also #322.
