When no locations have been created yet, the locations application shows a fairly unhelpful piece of "No locations found." text at /locations/.

Instead, it would be nice to show a more friendly state for new users, like this one:

If you've already created some locations, you can access this UI in these ways:

• Implement T12007 first, then destroy all the locations you created.
• Enable phabricator.developer-mode, then use Use Results → Show New User State in the upper right.
• Hack the code so the Query returns no results.

To improve this UI:

• Implement LocationsLocationSearchEngine->getNewUserBody(). You can follow ManiphestTaskSearchEngine as an example.
• Take a screenshot of the improved NUX and include it in your test plan.
