Hide the resetButton by default for Phobos examples

[wilzbach]

BTW, I noticed something a little weird - the "Reset" button is visible by default, but it goes away after you click it once.

If all PRs could be as simple as this one ;-)

Thanks for your pull request, @wilzbach! We are looking forward to reviewing it, and you should be hearing from a maintainer soon.

Some tips to help speed things up:

• smaller, focused PRs are easier to review than big ones

• try not to mix up refactoring or style changes with bug fixes or feature enhancements

• provide helpful commit messages explaining the rationale behind each change

Bear in mind that large or tricky changes may require multiple rounds of review and revision.

Please see CONTRIBUTING.md for more information.
