RegisterFactory passes parent container in delegate/factory

This is also the case with using the RegisterType with the obsolete InjectionFactory. However, this is a change of behavior because InjectionFactory used to give you the container/child that was doing the resolution of the outer type. I've confirmed that was the behavior back in at least version 5.8.13.

This behavior is a side effect of scope handling in child containers.

Encountering this behavior in v5.11.10
