Let reader the know they have to refresh IndexedDB to see new entries

Hey Alex, thank you a tons for this tutorial. This is more of a suggestion, which I think would especially help newcomers like me.

When I modified your code to add data for my project, it looked as if no data was added at all. The original data from your example was still there. But turns out they were added, but I had to click 'Refresh database' to see my newly added data (from this StackOverflow answer).

I think adding that clarification would really help someone who's only used DB's that instantly shows newly added data (like Firebase in my case).
