Keep Hit Area when Disabling AwesomeMap

Consumers want to have events flow to subscribers, but also
want to prevent any interaction from transforming the map.

Unit Tests
-------------

- Changed disabled state tests.

How To +10/QA
-------------

```bash
# skip the following steps if you've already initialized the project
$ git clone git@github.com:WebFilings/wf-uicomponents.git
$ cd wf-uicomponents

# do not skip these!
$ git fetch && 
git checkout keep_hit_area_on_disable && 
./init.sh && 
grunt qa
```

- Should see no console errors.
- Open the ScrollList demo. Check "disabled" at the bottom. Should not be able to directly interact with mouse or touch, but using the zoom and page controls still work as expected.
