This only works in addon projects

[trabus]

Due to the nature of how the emberApp helper sets up a test, and how blueprints are discovered, it's not currently possible to use blueprint test helpers inside a regular ember-cli app (the blueprint isn't able to be discovered in the temp project).

We should determine if adding support is desired or necessary, or if simply stating that it only works inside addons is okay.

this seems like a rare edge case to me. if it's possible to support this without adding much more complexity to the project we should do it, but if it means that we have to double the complexity I wouldn't think it's worth it.

I think we need to revisit this for v2-addons.
