Tutorial Bug: playground doesn't update on transition from Universal Reactivity to Default Values

[jbranchaud]

Here is the buggy state, notice that the playground still corresponds to the files/code from the previous step in the tutorial.

When I refresh the page, then I get the correct playground files/code loaded.

It happens on all pages. Provided you have the editor focused on any file other than App.svelte, clicking on the next will still leave the editor from the previous exercise.
