Add null validations for Test

[diegoveloper]

When we didn't setup the method channels and mock method handler in Test the tests failing because there is no validation on _translations.

 var translation = _getTranslation(key, _translations);

in that scenario _translations is null and will crash when try to check the key :

map.containsKey(firstKey)

@diegoveloper you can achieve it with Localization.load(<String,dynamic>{});
