Shindere/adding test for country

@jzoldak 
It would be clearer to use the [`override`](https://docs.djangoproject.com/en/dev/ref/utils/#django.utils.translation.override) context manager rather than `activate` and `deactivate`:

```python
with translation.override(user_language):
    # do test here
```

That way, you don't have to worry about possibly forgetting to `deactivate` the language at the end of the test.
