> When the component's state change, iPOJO loops on the handlers list and call the stateChanged method on each handler. But the order of call is the same than the handler starting order. 
> A problem occurs  when the stopping lifecycle callback handler uses a service dependency, the service dependency handler is "stopped" before the lifecycle callback handler. So, the callback call the dependency, but the dependency manager does not maintain service list anymore (it is stopped) and return null.
> Thie fix has two parts : 
> 1) modifiyng the internal handler order 
> 2) loop in reverse on the handler list in the setState method and stop method (ComponentManager class).
