Fix motion detection status check

[zagrim]

This should fix motion detection check and make working schedule work as it did in the Python 2 releases.
Thanks for @Marijn0 for pointing out the flaw in the code.

I've not myself tested this, hopefully someone using working schedule can do that.

Fixes #2663

@MichaIng the vulnerability causing failing the safety check looks to me like something that should be ignored, right?

Works fine:

Uh, indeed:

Camera 1 Detection status ACTIVE

Many thanks 👍!
