message: [now-cli] Fix for RangeError invalid count value
  This PR fixes a [sentry error](https://sentry.io/organizations/zeithq/issues/1611628097/events/75ed28bc6aef42868721a0912875fdbd/) where `repeat()` is passed a negative number and throws [`RangeError: invalid count value`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Resulting_string_too_large).
  This PR ensures `repeat()` is always passed 0 or greater.
