Breaks fastboot

[vlascik]

I'm trying to use this addon in a fastboot app, but there is a problem:

ember-error-handler: ErrorHandlerError: Consumer service:ember-error-handler/consumer/wsod-consumer failed
    at get.some.consumer (P:\Project\tmp\broccoli_merge_trees-output_path-2TWjWeAE.tmp\assets\addon-tree-output\ember-error-handler\error-manager.js:90:1)

    at Class.consume 

In ember-error-handler/addon/consumer/wsod-consumer.js line 59, there is a call to component.append();, which calls

_Mixin$create.append = function () {
    return this.appendTo(document.body);
  },

document doesn't exist in fastboot, so this breaks. Maybe there is a different way to add the component, that wouldn't break fastboot?

Probable cause is here.

I am currently busy on project. So I am unable to fix it. But feel free to give me pr.

Thanks for report.
