Update brightness with state `NULL` is not working, `execute_if_off` not working

[Danit2]

What happened?

Since the last update, the function execute_if_off no longer works.

I think it is related to this fix: https://github.com/Koenkk/zigbee-herdsman-converters/pull/9284

If I currently send a payload with the following content, the lamp switches on. {"brightness": 179, "state": null}

Thank you very much

What did you expect to happen?

I expect, that i can change the brightness without to turn on the light.
