Fix android livesync with sockets

[Fatme]

Fixes the following problems with android livesync with sockets:

1. Ensure .end is always called.
2. Don't use doSync in refreshApplication - in case doSync fails and is called inside refreshApplication method, {N} CLI will not stop livesync.
3. Call await doSyncPromise.then(...)
4. Call socket.destroy() in order to fix ctrl +c problem with node version < 10
