Bug fix Release - Reuse Containers

This is a small bug fix release where the service hooks was not invoked when ReuseIfExist was enabled and the container was reused. Now it will add the hooks to those as well and thus it will drive the State flow and execute any hooks attached. For example the below example would not invoke the CheckConnection prior this release.

Cheers,
Mario
