BuildShortcutInfoFromBundle actually reads the bundle from the file system,
which isn't ideal. Would web_app::ShortcutInfoForExtensionAndProfile not work?
It gets all the details you need on the UI thread.

Also, I think it would be neater if RevealAPpShimInFinderForApp can be called
from the UI thread, and posts to the FILE thread if it needs to.

Done. When using web_app::ShortcutInfoForExtensionAndProfile, turns out the
app_path didn't exist at creation time and so nothing was being revealed. The
RevealAppShimInFinder function has been modified to check if the app_path exists
first, otherwise reveals the directory above it.

+      app_data_path, shortcut_info, extensions::FileHandlersInfo());
+  shortcut_creator.RevealAppShimInFinder();
