Subject: [PATCH] Catch and noop call to open web browser. (#964)
Running `create-react-app` in a Docker container causes an unhandled rejection error in nodejs > 6.5 because the `opn` module tries to open a web browser in a system that doesn't have one. I figured this error could be safely ignored.
