fix: fix tns deploy ios --justlaunch when there are connected device and simulator

[Fatme]

NativeScript CLI doesn't respect correctly the built application package when there are connected device and simulator. That is the reason why tns deploy ios --path TestApp --provision NativeScriptDevProfile –justlaunch throws the following error: ENOENT: no such file or directory, scandir '/Users/mivanova/Projects/TestApp/platforms/ios/build/Debug-iphonesimulator'
