Unable to traverse some ember data relationships in the Inspector

[christophermlne]

Looking at the screenshot of the ember inspector UI, I can click through the ancestors relationship, but not any of the others that are identified as <DS.PromiseObject:...> or <DS.PromiseManyArray:...>. Clicking on those relationships causes the warning included below to be printed to the console.

This is likely a bug in the inspector itself.
You can report bugs at https://github.com/emberjs/ember-inspector.
Error message: Assertion Failed: You attempted to access the `_debugInfo` property (of <DS.PromiseObject:ember2256>).
Since Ember 3.1, this is usually fine as you no longer need to use `.get()`
to access computed properties. **However, in this case, the object in question
is a special kind of Ember object (a proxy). Therefore, it is still necessary
to use `.get('_debugInfo')` in this case.**

Hi @christophermlne, thanks for letting us know about this. It looks like the issue is here

ember-inspector/ember_debug/object-inspector.js

Line 704 in d865fec

if (object._debugInfo && typeof object._debugInfo === 'function') {

Would you be interested in working on a fix?

@rwwagner90 I will have a look at it tonight after work and report back
This looks straightforward. I will submit a PR tonight or early next week.
