Summary:
PR #17284 (accepted in 2ad34075f1) introduced a couple of regressions.
~1. There's the code:~
```
.then((appName) => resolve(selectedSimulator.udid, appName));
/* ... */
.then((udid, appName) => {
```
~~This makes `appName` to be always `undefined` as per `resolve` accepts only 1 argument. This regression causes issues if an app name differs from a scheme name.~
~This PR fixes this by wrapping both values in an array.~
This was fixed in 589eae1432.
2. The code
```
child_process.execFileSync('xcrun', ['simctl', 'boot', selectedSimulator.udid]);
```
makes a simulator *boot*, but the simulator *doesn't launch*. That's a regression, which forces developers to launch simulators by other means (by running a number of elaborate console commands, by running Xcode, or by running a simulator manually).
This PR reverts that part of changes.
Create a blank project with a name that differs from scheme name. Try to `react-native run-ios` in it. See that a simulator is launched and installing succeeds. Without this changes simulator wouldn't launch, and installing step would fail because of app name mismatch.
