Fix crash in NetworkServiceManager.

- Fixed a crash in NetworkServiceManager, which is listening to the activities' lifecycle of the whole app. The issue is that it was expecting a call to onActivityCreated where the Bundle was never null and that is a problem because the Bundle can most of the times be null during normal behavior. The Bundle isn't null only when the app is recovering from a forced process dead, which happens when there is another app open which requires resources and the systems kills apps that are not being used at that moment.
