Segfault when post mutation is disabled and the states are removed due to max gen test per mutant.

The problem lies in the function Executor::ks_eliminateMutantStatesWithMaxTests

The problem occurs when there is only one mutant. KLEE would optimize the mutant selection switch into LLVM br (if), causing the crash for some reason. (not that the crash does not occur if there is a var initialized with a constant right after the sym var assignment).

Temporary Solution: Make sure that there is at least two mutants.

Fix: Do not call Executor::ks_eliminateMutantStatesWithMaxTests when comparing outenv
