WeatherInformation: conditions after AsyncTask

WeatherInformation: conditions after AsyncTask

Before updating UI with data coming from AsyncTask through BroadcastReceiver we
must verify the data are the same as the ones that triggered the AsyncTask

I am trying to avoid this case:

1. Conditions trigger AsyncTask 1
2. Screen rotation (or any other thing that creates new instance of our Fragment)
3. Conditions trigger AsyncTask 2
4. AsyncTask 1 ends with success. Updates UI.
5. AsyncTask 2 ends with error. Show error message. <-------- PROBLEM!!!!

If before updating UI we check the current values, we may avoid the error created by AsyncTask 2.
