fix(ios): fix crash when --mode is specified

[tido64]

Summary:

Assumptions about where the .xcodeproj lives causes checkIfConfigurationExists to crash because undefined was passed as project.

Test Plan:

git clone https://github.com/microsoft/react-native-test-app.git
cd react-native-test-app
npm run set-react-version 0.72
yarn
cd example
pod install --project-directory=ios
yarn ios --mode 'Debug'

The last command should not crash.

I don't know if this warning is actually useful. I'd prefer to not have it here, but I'll let you decide.

Super strange that example workspace don't have configurations field present when we list them... 🤔

That is because the CLI is trying to look for .xcodeproj where .xcworkspace currently lives. That isn't always the case. Podfile and .xcworkspace are the only two files you can make assumptions about. .xcodeproj can live anywhere. The only way you can find it is by parsing the .xcworkspace, but it may contain several.

Yeah, got it. Still, one would hope that xcodebuild -list would output all configurations but it does not :|

I'll try to look at your PR ASPA, seems like interactive mode is broken as well since it's also calling getProjectInfo function...
