Done. I've moved this logic to chrome_native_app_window_views_aura_ash.cc which
could use ash dependencies.

+  Profile* profile =
+      Profile::FromBrowserContext(app_window()->browser_context());
+  if (profile && chromeos::IsNoteTakingApp(app_window(), profile))
+    appType = ash::AppType::DEFAULT_NOTE_TAKING_APP;

   // The frame insets are required to resolve the bounds specifications
   // correctly. So we set the window bounds and constraints now.
