i'm not really sure how that built at all ... since there is no device tarball anywhere for this image (ubuntu-device-flash should have failed) ... as you can see in the RPi2 section on https://developer.ubuntu.com/en/snappy/start/ you need the "device- pi2-*.tar.xz: device tarball" from http://people.canonical.com/~platform/snappy/raspberrypi2/ to get the RPi2 kernel into the image, i assume your image has the -generic kernel from the archive now.
