This issue is reproducible on Android device/emulator and iOS device.

Steps to reproduce:

1. tns create appTest
2. tns platform add android --path appTest
3. Make a change and execute tns livesync android --path appTest
4. Make another change and execute tns run android --path appTest

Result: the app synced at point 3 is started.
Expected: the app run at point 4 to be started.
