FELIX-5155: Do not invoke update callback in case the component implementation is an internal adapter object.
We don't invoke the callback in such a case, because if the update callback has been declared with an external
callback instance object, then calling the callback now would end up in a double update callback invocation: 
The update callback instance would be called a first time by the configuration dependency added to the internal adapter object,
and it would then be called a second time by the same configuration
dependency copied from the internal adapter component into the actual component instance created by the adapter.
