ember-exam: TypeError: Cannot read property 'on' of undefined

I ran ember install ember-exam on a relatively simple Ember addon project, then tried out ember exam and this seems to crash when trying to run the tests:

        this.process.on('processExit', browserFailureHandler.bind(this));
                     ^

I was able to reproduce the error. I will put a pr for a fix and have it release asap

fyi, a pr is being worked on and reviewed https://github.com/ember-cli/ember-exam/pull/388

@jherdman so the problem is this.process is not available when a browser is launched manually. I will put a pr up to validate whether this.process is available when registering events for processExit and processError.

@MichalBryxi ember-exam@4.0.3 has an issue, do you mind trying v4.0.4 and let me know if you are seeing the same issue?
