Make organization_list.dart multilingual

[palisadoes]

Describe the bug

1. We need to make the error message displayed in lib/widgets/organization_list.dart multilingual to support our internationalization efforts.
2. We should remove unnecessary print statements in the file
3. We should also make sure that the test coverage for the file gets as close to 100% as possible

To Reproduce

The most obvious section of the code can be found here:

            print("is empyt or nt");
              print(model.organizations.isEmpty);
              if (model.organizations.isEmpty) {
                navigationServiceLocal.showTalawaErrorDialog(
                  "No organizations found ! Please contact your admin ",
                  MessageType.error,
                );
              }
            });
