Existing external library files aren't being scanned.

The bug

After upgrading from v1.115, my external library assets show up in trash as offline. However, they can not be restored and still show as offline after a library re-scan. The server was upgraded with these assets offline already, that could be the issue. When clicking restore all on the webpage it says "restored 0 assets" and reloads the view with the offline assets still there.

Creating a new external library with the same import paths recognizes the files correctly. If I add new assets to the existing external library location they are recognized properly as well.

Reproduction steps

1. Have an existing external library on 1.115 (with offline assets)
2. upgrade to 1.116
3. assets are offline still and can not be restored or re-scanned in

Additional information

regarding the log, the scanned library already has 7 non-offline assets in, and more that show up as offline log is taken when scanning the existing external library
