Project cleanup

* Fix tabbing in loopback/index.js

* Remove unused gherkin.ts in root test directory

* Lexical order global type definitions

* Group test dependencies (expect/sinon) into single global file in root
  test directory

* Modify both mocha.opts to import single global file instead of
  expect/sinon separately
