Imports should be ordered :) (`import`, then `from`)

```python
import ui_navigate as nav  # And sometimes, when we seem to have lots of imports,
                           # we separate local and pip+std-lib imports, the latter first

from cfme.fixtures import pytest_selenium as sel  # This is the favoured way to import sel
from cfme.web_ui import Form, Tree, accordion, fill  # line 8, web_ui.Tree -> just Tree
from utils.update import Updateable
```
