Global decorators cause Storyshots to fail

[duro]

Surfacing this again from #877.

When I add a global decorator to .storybook/config.js it cuases my Storyshot tests to fail with:

src/components/__test__/Storyshots.test.js
  ● Test suite failed to run

    Global decorators added after loading stories will not be applied

Here is a simple workaround which mocking addDecorator as an emptyFunction in my project.

// Storyshots.test.js
import initStoryshots from '@storybook/addon-storyshots'

const sbReact = require('@storybook/react')
sbReact.addDecorator = () => {}

initStoryshots()
