This PR added the cron.manager dependency to the controller.helper service. This can lead to cyclic dependencies when a cron task depends on the controller.helper service. I've attached a minimal extension to reproduce the problem. The issue is not limited to extensions though.

Expected error message:

Circular reference detected for service "kasimi.circrefin331.cron.task.sample", path: "kasimi.circrefin331.cron.task.sample -> controller.helper -> cron.manager -> kasimi.circrefin331.cron.task.sample".

Real world example: while having both mChat and ABBC3 extensions enabled, mChat's cron task can't be executed and throws an error because of circular references:

dmzx.mchat.cron.task.mchat_prune
-> text_formatter.s9e.parser
-> controller.helper
-> cron.manager
-> cron.task_collection
-> dmzx.mchat.cron.task.mchat_prune
