Jest throws React.createElement: type is invalid when using CachedImage in any List component

Was finally able to figure out how to test this component.
Adding the following mocks to the either setupJest.js file or the individual tests should allow the react-test-renderer to render the Image component from CachedImage component. You can also specify another mock for the CustomCachedImage component, but this worked for me.

jest.mock('react-native-img-cache', () => {
  const mockComponent = require('react-native/jest/mockComponent')
  return {
    CustomCachedImage: mockComponent('Image'),
    CachedImage: mockComponent('Image'),
  }
})
jest.mock('react-native-fetch-blob', () => {
  return {
    DocumentDir: () => { },
    polyfill: () => { },
  }
})

@wcandillon Do you think its worth having this example in the Readme ?
