Fix Error on Ubuntu

[akindofyoga]

Running NPM start for the local version causes an error on Ubuntu. The following two posts on the Zoom developer form talk about this error:

1. https://devforum.zoom.us/t/installing-sample-app-web-gives-error/12103
2. https://devforum.zoom.us/t/unable-to-use-zoom-websdk-sample-web-app/15855

This change fixes that error. It will prevent the page from automatically opening in someone's browser. But Webpack already prints out a message saying Project is running at https://localhost:9999, so this doesn't seem like a big loss.

I also expirenced this problem under Fedora and this fix worked. Thank you. Maybe linux and webpack use a different command to open the web browser (since opening the browser from a create-react-app works fine)?
