Cleanup .travis.yml
Remove option to specify router

Since the following commit, there is a failing test:
* emberjs/ember.js@58fd8c71

The reason is that the checking for lookup object in container was landed.
* https://github.com/emberjs/ember.js/commit/58fd8c71ea677cd4e1e97de5d50b105e9ec0d92d#L0R589

To fix this test, I removed `router: false` from application config.
