Truncate response prefix

[tomschenkjr]

While troubleshooting #44 and #45, we have determined the best "fix" is to modify the response by dropping some unnecessary elements of the response. Namely, we will drop the items:[{"result": prefix and only return the fields within that result: element.

Thus, the new response will appear similar to this example:

{
"risk_score_notes": "1. Please follow protocol for lead safety.", 
"errors": [], 
"network_id": "Alliance Health", 
"timestamp": "2018-05-21 21:16:39", 
"clinic_id": "EF", 
"patient_id": "6425", 
"risk_score": "0.190358333333", 
"version": "1.0.0-rc.3", 
"location_id": "examp_loc"
}

This is consistent with the published documentation.

Please remember to increment the version field to 1.0.0-rc.4 as this change is made.

I opened an issue to this effect in the runner.
