Prevent writeDataToDisk calls when switching from guest user to primary

user

Previsouly, we were only listening to ACTION_SHUTDOWN event, which is
triggered whenever 'user' on Android is changed. This will fire an
intent to write a file to disk and it is not intended. So we add
an additional check to see if the ACTION_SHUTDOWN is on foreground as
user switch fires ACTION_SHUTDOWN is NOT on foreground.
