when app is closed and make a change, it doesn't open

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: rc(5.2.0-2019-02-07-12917)
• iOS Runtime:5.1.1

Describe the bug
App is successfully synced but it not loaded

To Reproduce

1. tns create appNG --ng
2. tns run ios --hmr
3. make a change in css file. The change will apply correctly.
4. close the app from device as press home button.
5. make a change again in css file you will see that the app doesn't open but console logs are:
   Refreshing application on device f42eb590ec7ad920c8c0545a308e1a1d2551218b... Successfully synced application org.nativescript.appNG on device f42eb590ec7ad920c8c0545a308e1a1d2551218b.

Expected behavior
the app must open and work correct

Inizia eseguendo tns info, quindi riproduci il problema con tns create appNG --ng e tns run ios --hmr. Modifica un file CSS mentre l’app è aperta, chiudi l’app e modifica nuovamente il CSS. Il lavoro è completato quando l’app iOS si apre e funziona dopo la seconda modifica, invece di limitarsi a segnalare una sincronizzazione riuscita.
