getApplications(...).mapBy is not a function

Prototype extensions are disabled in my project.

Version: 3.5.0

Seeing this when I link canary against my app. This probably came from #898
It seems the responsible line is here:
https://github.com/emberjs/ember-inspector/blob/master/ember_debug/vendor/startup-wrapper.js#L135
I think we could change that line to .map(item => item && item.name).
I can try fixing this later today or if anyone else wants to now :)

NVM, just figured I'd get it now. I manually tested this locally and it solved the issue. I'm curious how to stub no prototype extensions in the acceptance tests.
