Delete /data/local/tmp/<app-identifier> file if exists on Android device

Livesync does not work when /data/local/tmp/<app-identifier> file exists on Android device.
This happens when a file with name app-identifier exists in /data/local/tmp directory on device. In this case CLI is not able to create directory.
