Error when locationType is not hash

[jakecraige]

To work on a device, locationType must be hash. We should error out on the build if it's not.

Would have saved me a week of frustration when I first transitioned to ember-cli if I’d realized the default was auto and what that had done to me. The error you in the safari browser get is pretty generic and could relate to any number of whitelist problems, build target issues, etc.

Yeah I just helped @irjudson debug this in IRC and I realized that it's something we can catch in the build and prevent from happening to anyone else.

this gave me an issue as well, but when i used the blueprint it wasn't an issue anymore.
