ImageStreamCompleter._checkDisposed fails in production app

[LucasG04]

Crashlytics catches an error several times lately when loading images which causes the app to crash. The reason for this error seems to be this: Baseflow/flutter_cached_network_image#785

There is already a solution that needs to be applied: Baseflow/flutter_cached_network_image#777

Adjust pubspec.yaml like this:

  cached_network_image:
    git:
      url: https://github.com/SuaMusica/flutter_cached_network_image.git
      ref: feature/errorListener
      path: cached_network_image
