Trigger auto-slice based on stackValidation instead of stack/setting changes

Browse source 
CURA-4084

Stack error checks are scheduled with a delay, and when a container is
changed (e.g. Quality), the auto-slice may get triggered before the
error check is done. Because the error check result is cached, the
auto-slicing will use the previous result instead of new. So, the
auto-slicing should be triggered when a stack validation is finished
instead of when a stack/setting gets changed.
