fix(resolver): allow custom fallback ID effects

Add a missing step to the effect resolution flow. If a user has no
custom effect defined by name/LID, and the module does not define an
effect by LID, allow the user to define a custom effect by fallback ID
before finally resorting to the module's effect for that fallback ID.
