Don't emit changed signals if the global stack ID doesn't exist

Browse Source

This is equivalent to putting the call to self.__emitChangedSignals() in the if-statement. But I switched the condition of the if-statement around because it looks more like error handling to me. This is the main case.

Contributes to issue CURA-5045.
