https://greenkeeper.io/

* chore(package): update eslint to version 3.12.0

https://greenkeeper.io/

* Update eslint-plugin-import to v2.2.0

New minimum version to satisfy the peerDependencies of
eslint-config-airbnb-base.

* Don't await in a loop

Fix the only lint issue from this update by moving the resolution of the
invalid trace promise to the very end, out of the loop.
