Component that fails to start should be unregistered

When a component fails to start it is still registered and can be used by other components or during the repository initialization.
The result can be a corruption of data because services the service of component that is not initialized might produce an unexpected result, like in NXP-29706 where codec initialization is not done resulting in the corrupted stream.

So if a component fails to start it should be unregistered, better to fail fast and clear.
