swaggerize-express@^4 brings in "enjoi": "^1.0.0"
https://github.com/krakenjs/generator-swaggerize/blob/master/app/templates/_package.json#L21

However the generated app's dev dependency on enjoi is stuck at an older version making the unit test fail.

Generated APP: https://github.com/subii/swaggerize-examples/tree/master/petstore-simple-express
