Nested .app Files Are Missed During Installation

[pradeepjunglee]

Unity.app is packaged with Myapp.app, and I verified this using the pkgutil --expand-full Myapp-14.44.47+14.pkg app command. However, during installation, Unity.app is not found. Here are the relevant logs from install.log in Console.app:
