perf: remove redundant 6k ± 1 check in IsPrime

Browse Source 
No integers >3 satisfy the condition of being odd AND not being a multiple of 3 (as checked above) AND not being in the form 6k ± 1. This condition never evaluates to true, and so the return is never reached and was preventing this method from hitting 100% code coverage.
