Property "_store" not present in production React Elements

[chen-ye]

react_fast_compare checks for the existence of _store in order to verify the compared object is a React element, and avoid react-specific circular references.

However, this property is not created in production environments (as can be seen at https://github.com/facebook/react/blob/master/packages/react/src/ReactElement.js#L126).

As a result, react_fast_compare doesn't omit circular references in production.

Here's a reproduction Works fine in dev environments: https://codesandbox.io/s/nk6rzr7z64 But fails to omit _owner in prod: https://csb-nk6rzr7z64-cfyxlokhrg.now.sh/
