random reporting compilation returns if counterexample is genuine or potentially spurious, and takes genuine_only option as argument

the reporting random testing also returns if the counterexample is genuine or potentially spurious

exhaustive returns if a counterexample is genuine or potentially spurious in the presence of assumptions more correctly

inverted flag potential to genuine_only in the quickcheck narrowing Haskell code
