Blocking desktop synchronization for folders results in logging all instances of "block access" in Nextcloud 18

[Dave-REBL]

Steps to reproduce

Add restricted tag "NoSync"

Create file access rule (Block Desktop Sync)

Rule 1: File system tag is tagged with NoSync (restricted)

Rule 2: Request user agent is Desktop client

Tag a folder containing other folders and files with "NoSync"

Share the tagged folder with a user using Desktop Client 3.0.3

Upgrade from Nextcloud 17 to Nextcloud 18

Expected behaviour

Rule is working as expected, but should not be logging every single instance of blocking access to a file, repeated every 30 seconds.

Actual behaviour

The work flow engine is logging every single instance of blocking access to a file, repeated every 30 seconds to nextcloud.log.

Note: These are Info logs. Changed logging level to Warning (2) to avoid filling up the log but this is not a solution as other Info logs are required.

These log messages were not generated in Nextcloud 17.
