Create tests for the new APIs

[francisli]

The codebase now has a test for the Resources API- it's in test/routes/api/resources.js.

To run tests, log in to a running server container and perform these set up steps:

$ sequelize db:create --env=test
$ sequelize db:migrate --env=test

These commands create and migrate the TEST database. Then, to run ALL the tests, you can run:

$ npm test

To run a specific test file, you can specify it as an argument to the mocha test runner command:

$ mocha test/routes/api/resources.js

@JesusEArambula in the last PR I merged from you, I added a test file for the Resources API. See if you can run the tests by following the instructions in this issue. Let me know if you have any questions...

A good way to learn more would be to see if you could create new tests for the other new APIs we've created- i.e. Categories API, Forms API, etc...

The reason I think this is an interesting topic to introduce now is that, this is one way to check if things are working in the backend (i.e. is the Resource description saving properly?), without having to manually log in to a running server and fill out forms by hand, etc.
