Missing subcriptions management on auth component

Could the missing subscription management on the auth component create some leaking problems? Is it OK to do it like this in a real-world app?

@carballosa Sometimes that is OK to not unsubscribe (where the source of the observable will relinquish the resource). I've created a PR to put a context on this: https://github.com/gothinkster/angular-realworld-example-app/pull/153 The note here explains this: https://angular.io/guide/router#observable-parammap-and-component-reuse Also check Ben Lash comments from Ng Conf closing panel: https://www.youtube.com/watch?v=PjHIqx0w4do Cheers!
