lazy initialize the ScorerUtil DEFAULT_IMPACTS_ENUM_CLASS to prevent
initialization issues with this class if the thread gets interrupted.
### Description
The ScorerUtils fails to initialize if a thread gets interrupted right when
it executes its static initialization routine.
One has to restart the JVM then to make it work again.

I made the patch so that it will ignore double-initialization of that
constant in case of multithreading. I thought it is not worth to tackle with
that in that scenario.
