On a completely clean Xcode install (such as those provided by CI platforms), the iOS test simulator set can be empty. The iOS simulator management tooling will return error code 1, rather than an empty list of simulators in this case. This prevents the testbed from starting.
This PR catches the return code of 1 and returns an empty list of simulators, so that the simulator detection part of the testbed script can operate as intended on a CI configuration.
