AbstractSplittableWithBrineGenerator does not create a random salt

Summary

The salting function for random spliterators produces a constant (same) result.

Problem

The implementation has a "not equals" condition in the iteration portion of the algorithm when it should be "equals".

Solution

Correct the condition.
