Refactored tests slightly.
Adding pause to travis-ci script to allow mongodb to start and connection to be established.
Cleaning up REST api and better-utilizing HTTP status codes. Returning 'href' property on resource-creation. Updated tests accordingly.
Added 2 tests, each to fetch a specific user/tournament.
Storing resource href on db-write, instead of re-calculating on db-read.
WIP changes to API and tests' serviceWrapper.js
