26/50] Fix check for `get`/`set` recommendation (#34885) * Added more tests. * Accepted baselines. * Work better with any parameter type. * Accepted baselines. * Use the actual indexed expression. * Add tests that exhibit bad stringification. * Accepted baselines. * Short-circuit stringification on 'undefined'. * Accepted baselines. * Remove space. * Accepted baselines. ---
