fetch calls (apps, examples) => then, catch order

old:

        fetch(url)
            .then(response => response.json())
            .then(data => me.addStoreItems(data))
            .catch(err => console.log('Can’t access ' + url, err));

new:

        fetch(url)
            .then(response => response.json())
            .catch(err => console.log('Can’t access ' + url, err))
            .then(data => me.addStoreItems(data));

we only want the catch error for failed requests and not for errors inside the callback.
