LPS-33340 We should not be passing back a JSONObject that contains a bunch of JSONObjects keyed to empty values. We should instead pass back a JSONObject that contains a JSONArray. It saves on network transfers (and makes more sense). The frontend autocomplete component ought to be smart enough to take in both a JSONArray or JSONObjects. You can call A.hash to quickly convert a list of JSONArrays to a list of JSONObjects (according to Nate).
