ERROR Circular reference detected trying to get service {...ThingProvider, ...YamlThingProvider, ...YamlModelListener}

Often I see the following stacktrace when starting a recent 5.0.0-SNAPSHOT (build # 4638):

[openhab-bot]

This issue has been mentioned on openHAB Community. There might be relevant details there:

https://community.openhab.org/t/openhab-5-0-milestone-discussion/162686/84

[wborn]

Perhaps it's caused by #4691 as it introduced the yaml thing dependency @lolodomo?

[lolodomo]

It is fixed by #4753
I hope someone will review it soon...
This PR is also blocking other developments that I based on this fixed version without circular reference.
