No "paint" property in styles causes edit mode to crash app

[rossjs]

When creating a new layer, you have to manually add a paint: {} property/object in order to prevent app from crashing.

If not, you will receive the following error:

Uncaught TypeError: Cannot read property 'keySeq' of undefined

To add to this report, you can recreated it by clicking the edit arrow on a layer that does not have a paint:{} property.
