Housekeeping of files which are deleted or no longer exist

Steps to reproduce

1. Add a file through the UI
2. sudo runuser -u nginx -- php -f /nextcloud/html/cron.php
3. Check oc_files_antivirus table which should now include the new file
4. Delete file through the UI
5. sudo runuser -u nginx -- php -f /nextcloud/html/cron.php

Additional steps to try and invoke the intended behaviour

• Update check_time for the file to be beyond 28 days

Expected behaviour

The oc_files_antivirus table should no longer have an entry for the file

Actual behaviour

The oc_files_antivirus has files which no longer exist and no house keeping performed

Start with the cron.php execution described in the reproduction steps and trace how entries in the oc_files_antivirus table are created and checked using check_time. Reproduce the sequence with a deleted file, then verify that running the cron job after the relevant time threshold leaves no entry for that file.
