Convert all prints to logs

[guyluz11]

Follow up to #59 we now need to convert all the pints in the app to use the new log system that we have added.

Just use logger.i('Text'); instead of print('Text'); and import the logger function from
import package:cbj_hub/utils.dart';

Here are the types of log that you can use

logger.v("Verbose log");

logger.d("Debug log");

logger.i("Info log");

logger.w("Warning log");

logger.e("Error log");

logger.wtf("What a terrible failure log");

Thanks @BangBuster is that all the prints or there are more left?

@guyluz11 the last PR was only for the error prints, if you find any I missed, let me know!
