Fix org & loc creation functions and improve error message for api.

Improves error message for enable_rhrepo_and_fetchid in api.utils.

The indent for submit button for org and location functions is now
fixed.
Also now org and location CRUD functions have flat code and no
generic exceptions.
What about:

```python
proceed_to_edit = self.wait_until_element(locators["location.proceed_to_edit"])
if proceed_to_edit is not None:
    proceed_to_edit.click()
```

I'm not aware of any caching done by Selenium, because that I think caching the element result would be faster. I'm doing the analogy of the `wait_until_element` being a kind of network operation.
