Elasticsearch queries via kinto-elastic trigger ES 500 errors in Sentry

[peterbe]

See https://sentry.prod.mozaws.net/operations/buildhub-prod/issues/753794/

This can happen from running a ES query like this:

echo '{
  "query": {
    "bool": {
      "must_not": {
        "regexp": {
          "target.version": ".*rc\d+"
        }
      },
      "filter": [{
        "term": {
          "target.channel": "release"
        }
      }, {
        "term": {
          "target.locale": "en-US"
        }
      }, {
        "term": {
          "source.product": "firefox"
        }
      }, {
        "term": {
          "target.os": "win"
        }
      }]
    }
  },
  "sort" : [{
    "build.id": "desc"
  }],
  "size": 1
}' | http POST https://buildhub.prod.mozaws.net/v1/buckets/build-hub/collections/releases/search

The output of that httpie query is actually 200 OK from the outside.
