Shallow API setContext should work without static contextTypes for React 16

[eugef]

According to the latest React documentation static contextTypes is no more needed for Context API to work - only static contextType (single form here) is needed https://reactjs.org/docs/context.html#classcontexttype

Current behavior

Enzyme for React 16 still requires static contextTypes to be defined to make setContext() work.

Expected behavior

Enzyme for React 16 should only rely on static contextType.

enzyme doesn't yet support createContext at all (nor contextType) - see #1553.

Ok, got it

Just wanted to plug facebook/react#14329 - I put a PR out for the shallow react-test-renderer so that when contextType is defined, you can just pass it a context. I could be wrong, but once that's merged + released, enzyme should be able to bump the version, and context should work on render.

I need working solution for static contextType. I didn't find how should be work with dive or wrappingComponent for PR so I created module for workaround https://www.npmjs.com/package/shallow-with-context. The module works well in our projects.
