Update no election text logic

[Bekabyx]

Closes #1694

The logic for this was totally broken, referencing variables that seemingly weren't in the page payload. As this message should only be displayed when there are no elections to show, I've simply moved the html up to the same conditional block that is responsible for the "No elections in your area" text.

This means there's a slight change in text order on the "No elections" style page, but imo this looks fine.

To test:

• Run manage.py import_ballots --current if you're not totally up to date
• Use B773AE in the postcode search
• You should see the Elections in Your Area card without the "Local and devolved elections..." message

That postcode didn't work for me even after an import, but I was able to look at an upcoming election and did not see the text as expected. 👍
