Charting for custom geographic areas

Followup to https://github.com/GreenInfo-Network/nyc-crash-mapper/pull/72 This adds to the Trend and Compare charting, support for custom-drawn geographies.

• Trend offers this custom geography as a Benchmark Area for comparison. One still compares other selected areas against this benchmark.
• Compare has an always-present starting sparkline chart for the custom geography, and one may still select 2 more areas for comparison.
• In both cases, on the right-hand side is a custom geography area, allowing one to either go back to the map to draw a custom geography, or else to clear the existing one.

Hmm, when I run this locally and draw area, see charts for area, clear area, then click Draw Area again, the map loads but the data never does, with this in the console:

(index):1 POST https://chekpeds.carto.com/api/v1/map?stat_tag=API 400 (Bad Request)
index.js:178 Uncaught ["missing FROM-clause entry for table "a""]

I wonder if it involves unexpected or malformed URL params coming back to the map?

Here's the link I have:

http://localhost:8080/#/?cfat=false&cinj=true&clearCustomGeography&customGeography&endDate=2017-12&geo=custom&identifier=3&mfat=false&minj=true&pfat=false&pinj=true&setReferenceEntity=function%20%28%29%20%7B%0A%20%20%20%20return%20dispatch%28actionCreator.apply%28undefined%2C%20arguments%29%29%3B%0A%20%20%7D&startDate=2016-12

Seems like some of the stuff around setReferenceEntity are somehow broken. I suspect some of these params just shouldn't be present for the map.
