docs: To be called from the host {@link android.app.Activity}'s {@link
  android.app.Activity#onCreate}. Calls the registered {@link Bundler}'s {@link Bundler#onLoad}
  methods. To avoid redundant calls to {@link Presenter#onLoad} it's best to call this before
  {@link android.app.Activity#setContentView}.
