Changed the default mocha test name

Changed the mocha test name from test.js to test.spec.js.

Normally webapps have two different test suites. One suit for spec tests and one for integration tests. 
So I took the liberty of renaming the default test as spec test and adding a mocha-cli spec job. This makes it easier to add integration tests in the long run.

Also removed that bloody annoying automatic dependency installment for tests. :)
