Fix the issue with automatic app removal of apps on external disk
If the Oculus app is launched, without the external drive connected, the apps on the external disk will no longer be usable, and the user have to download them again.
This bug is particularly annoying because the oculus app starts automatically when any app uses the SDK.
I know that it is not recommended to use external drive, but using a laptop and the apps are several hundred gigs, I don't really have a choice.
There is no other app that I know of that has this behaviour, of course you cannot run the apps when the drive is not available, but when it is plugged back in, the expected behavior is that the apps can be accessed,
not that you have to download them again!
