Autocomplete results slowed by search endpoint's other queries

[andycochran]

What should happen:

When I search for a location, I expect typeahead results to come back from GeoSearch as quickly as they do on ZoLa.

What happened instead:

GeoSearch's fast autocomplete endpoint results are returned at the same time as all other search helpers, so they're bottlenecked by the slower calls to Carto.

How to reproduce this bug:

1. Search for an address
2. Wait… 💤
3. See autocomplete results.
