Tests are not working in Travis

When Travis runs a test, it ends with:

Build and installs are OK, but it fails on launching tests.

It's difficult to make this kind of complex applications to properly work in Travis due to workload and real time requirements, so we won't use in the future. Anyway, we'll include more accurate tests that can be run with the following command once installed:

npm test
