Broken export when using Webpack 2 (React.createElement: type should not be null)
See original GitHub issueIn 3.1.0 the export is not broken: typeof require('react-helmet') === 'function'.
In 3.2.0 it is broken: typeof require('react-helmet') === 'object'.
The error is “Warning: React.createElement: type should not be null, undefined, boolean, or number. It should be a string (for DOM elements) or a ReactClass (for composite components). Check the render method of Layout.”
The cause is that v3.2.x of ReactHelmet is { default: function ReactHelmet() {} } when imported in Webpack 2.
