Title: [Bundle] Lazy load loaders' callbacks

To have callbacks instantiated only when they are to be called.

The approach I had with the CompilerPass before was not wrong, but it had the disadvantage of instantiate all callbacks when the Loader was loaded. This PR avoid this, and makes the callbacks instantiated only when a transition is applied and the callback is to be called.
