[Tradfri] Illegal status transition from REMOVING to OFFLINE, only REMOVED would have been allowed.

[cweitkamp]

I got the following exception after removing one of my remote controllers from my setup. The device itself got broken while updating its firmware.

The stack trace shows some changes which will be introduced in my ongoing PR #4373 but the issue in general is not related to my changes. I want to ask you and discuss how to handle this error in the right way.

See #942 and #4182

So, I assume this can be closed as duplicate. Correct?

[cweitkamp]

Yes, it's clarified and duplicate. Thank you.

MEMO for myself: Use the search function next time!!! ;-)
