elasticsearch override doesn’t always work during complete re-index

[TanyaStere42]

Expected Behavior

Current Behavior

1. blow away ES index (on sightings)
2. rebuild as above
3. look at /api/v1/search/app.modules.sightings.models.sighting/mappings and see if location_geo_point has the overridden geo_point type.

when invoke app.elasticsearch.now --model Sighting is run on an empty index, it seems as though effects of patch_elasticsearch_mappings() do not stick. at least a few runs on a dev install seems to indicate this.
