feat(mutator): Add conditional operator mutator (#2583)
* feat(Mutators): Add conditional operator mutator Add conditional operator mutator Add tests for conditional operator mutator Include conditional operator mutator in mutations.md * Fixes to unit tests * feat(Mutators): Remove NegateConditionMutator's conditional expression mutation * Fix integration tests * Fix last integration test * ConditionalExpressionMutator should not mutate declaration patterns. Fix tests. * Fix ValidateStrykerResults compilation. --------- Co-authored-by: Michał Isalski <isalski.michal@gmail.com> Co-authored-by: Liam Rougoor <liam.rougoor@infosupport.com> Co-authored-by: Liam Rougoor <35850587+Liam-Rougoor@users.noreply.github.com> Co-authored-by: Rouke Broersma <rouke.broersma@infosupport.com>
