An occ groupfolder:scan becomes extremely slow

[Serial32]

Steps to reproduce

1. Enable "Files automated tagging" Plugin
2. Scan a groupfolder (for example occ groupfolder:scan 84)

Expected behaviour

The group folder is 23GB in size. If the plugin is deactivated, a scan only takes a few seconds.

occ groupfolder:scan 84
+-----------+---------+-------+--------------+
| Folder Id | Folders | Files | Elapsed time |
+-----------+---------+-------+--------------+
| 84 | 6202 | 39486 | 00:00:26 |
+-----------+---------+-------+--------------+

Actual behaviour

If the plugin is activated, the scan takes over 11 minutes, although the same content is scanned.

occ groupfolder:scan 84
+-----------+---------+-------+--------------+
| Folder Id | Folders | Files | Elapsed time |
+-----------+---------+-------+--------------+
| 84 | 6202 | 39486 | 00:11:46 |
+-----------+---------+-------+--------------+
