Title: Don't fallback to default apps when ImportError is raised

Thanks to dynamically loading apps, there is no need to override Oscar application and list your app. (But you can still do it if you want) Dynamically loading app fallbacks to standard Oscar application when ImportError is raised.

Be clever about ImportError and fallback only when imported app can't fe found (not when a dependency of that app can't be found)
