Basic location correction [PD-745]

I'm currently working on making tests pass, but it's a test issue, not a view issue.
Both:
```python
if cleaned_data.get('country') not in [
    "United Sates", "Canada"] and not self.instance.pk:
````
Or:
```python
if (cleaned_data.get('country') not in ["United states", "Canada"]
    and not self.instance.pk):
```
Or:
```python
if not all(cleaned_data.get('country') in ["United States", "Canada"],
             self.instance.pk):
```
