Summary: **Motivation** This morning I was trying to test on iPhone 7 with iOS 10 so I booted that device and ran "react-native run-ios" expecting it to notice I had a simulator running and install my app to it. Instead it switched my device to the iPhone 6s iOS 9.2. After digging it was found that run-ios did not handle multiple versions of iOS being installed very well when it came to checking for the booted device. This PR resolves that. **Test plan (required)** Tests were added for the situation of multiple iOS versions being installed and a slight change to the code was completed to make the new tests pass and continue to keep the old tests passing. Closes https://github.com/facebook/react-native/pull/10558 Differential Revision: D4163616 Pulled By: hramos fbshipit-source-id: 26b44fb73ef402ce252e7a754036279e15359170
