In GetInstancesFromServiceLoader, do not hide ServiceConfigurationError

In class GetInstancesFromServiceLoader, thrown ServiceConfigurationErrors are not logged:

There are cases where it would be useful if these were logged after all.
Take for example the case where a developer adding a new ConstraintValidator has made a mistake and has not provided a no-args constructor for the validator. ServiceLoader will in this case fail to load the ConstraintValidator, but this will not be obvious to the developer.
