Cleaning tmp build files

Leaves me without a /out directory.

FWIW, I'm getting the same error with my application (for/on Linux x64 platform). It works when calling ember electron but not ember electron:package

Enabling debugging for electron-compile shows:

I see this as well but I end up with the correct files in out/

Supposedly this is safe to ignore (see electron-userland/electron-compile#167), though these types of things make me crazy because it seems I always spend a lot of time chasing them.

@jacobq good too know. Leaves me with a different reason why I'm not getting any builds. Closing for now.
