Running "occ files:scan" ignores request to scan (and clear) a missing file

Steps to reproduce

1. Upload a test file to the Nextcloud instance
2. Delete the file from the underlying file store (NOT via Nextcloud)
3. Run "occ files:scan --path=[path to now missing file] to make it realize the file is gone
4. Observe that occ errors out with "Path not found: [path to missing file]" error rather than completing the requested action and updating/removing the missing file.

Expected behaviour

Nextcloud should recognize that while the file it thinks is there is gone from the underlying datastore, it still needs to correct its records and remove it from the filesystem view it presents to users/apps.

Actual behaviour

The occ command errors out with "Path not found: " error, yet continues to show that the file exists through webdav, which is an incorrect and unwanted inconsistency.
Attempts to access the file that appears to be there but isn't will continue to produce errors.

Additional Notes

This worked as expected on Nextcloud 9.0.58, which is what I was running before updating to Nextcloud 15 and then 16. Both Nextcloud 15 and 16 have this problem. I haven't tested later versions, but I would guess it might still be there as well.

There is an obvious workaround, which is to scan the whole directory that contains the missing file, rather than to specify that occ should scan just the file that is trying to be fixed/cleared. That is not a reasonable workaround though, because the scan takes a prohibitively long time and severely impacts performance of the system for that time if the containing directory has many other subfolders and hundreds of thousands of files.

Start with the occ files:scan command and reproduce the missing-file case using a targeted path rather than scanning its entire directory. Trace how the command handles a file absent from the underlying file store; done means the stale filesystem view is removed without the command failing on the missing path.
