Fix ember global

[chancancode]

A minimal fix for #600. We should probably follow through with the refactor suggested by @rwjblue in #600 but that can be done later.

This is probably not very embroider friendly, but neither is the current code. It's probably easier to just rewrite the shims in terms of ES modules and embroider macros, i.e. what was suggested in #337.

Hi @chancancode ,

This is probably not very embroider friendly, but neither is the current code. It's probably easier to just rewrite the shims in terms of ES modules and embroider macros, i.e. what was suggested in #337.

I had a similar problem when upgrading this package/dependency for mber. mber does bunch of hacks to get this dependency included in the fastboot environment, now I need to adjust the hack again for <%= templates.

Despite fetch coming to newer versions of node.js, I'll probably still need this package for runloop/testing awareness and its helpers functions. So I'd really appreciate if we can rewrite these shims in terms of ES modules and macros as soon as possible instead of relying on a broccoli dependent temporary solution.
