Fixed objc test runner and bezier test

Summary:
- kill -9 SERVER_PID does not work for packager currently because it is started as daemon.
- And lego tests just hang until they are killed e.g. intern/sandcastle/1952254070/187417721/
- fixed bezier test because it annoyed me with random breaks because of precision
