this._super() broken after this.reopen()

[Emrvb]

After a reopen() , super methods can no longer be called.

Works until (and including) 2.0.2
Broken in 2.1.1

PS.

Considering this is an edge case. Documenting this behavior or triggering a warning/assertion when calling reopen on a constructed class is a fix to me.

We had a similar issue that was fixed in emberjs/ember-inspector#481. Calling reopen on an instantiated class seems "weird" at best. I'm not sure that there is much to be done to actually fix the underlying issue here...

unsure if it is related but: this._super(); requires this._super.apply(this, arguments)

We want to kill this feature, as it can't reasonable be made to work correctly in all scenarios, and still be performant.

Well, removal and hitting "undefined is not a function" is also a fix that would have saved me an hour debugging :P.
