[Security Apps & Website] "Not a face" -> Error 10, missing device_id

Hello,

as the title says I have a problem which occurs in the security apps (both Android and iOS) as well as on the website: When I try to mark an "unknown person" detection as "not a face", I will get an error. It always has code "10" and on the website I can see this respsonse in the devtools:

{"error":{"code":10,"message":"Missing device_id"}}

I can see that the request contains a "home_id" and "person_id", but not a "device_id". This is weird, because I only have 1 room set up with only 1 Netatmo Welcome camera in it. 

For me it seems like the API was changed, but the frontends (Apps + Website) were not.
