- Updated .travis.yml to run a build against Node 4 LTS

- Updated package.json to collect latest jsonapi-server version 3.0.2
- Updated test/proxy.js to check if what we're attempting to require
from the jsonapi-server's test suite is a directory or not. Decided to omit
the latter files from require (as fixtures are used in the higher level tests
so not needed when requiring).
