title: apollo MockedProvider + Storybook not working
body: <p>Using MockedProvider in Storybook doesn't seem to return anything.</p>
  
  <p>When wrapping my component in the MockedProvider, it no longer throws an error that there's no Apollo client. So this proves that the MockProvider "works"</p>
  
  <p><strong>Intended outcome:</strong></p>
  
  <p>The following hook should return the data that's in the mock:</p>
  
  <p><code>const { loading, error, data } = useQuery(LATEST_SELL_SIGNALS)</code></p>
  
  <p><strong>Actual outcome:</strong></p>
  
  <p>loading is <code>true</code> on first render and <code>false</code> on the second render</p>
  
  <p>data is <code>undefined</code></p>
  
  <p>error is <code>undefined</code></p>
  
  <p>The fact that the loading props are working, should also suggest MockedProvider is running.</p>
  
  <p><strong>Example story:</strong></p>
  
  <pre><code>import React from 'react'
  import { MockedProvider } from '@apollo/react-testing'
  
  import { LATEST_SELL_SIGNALS } from '~/common/queries'
  import LatestSells from './LatestSells'
  
  const mocks = [
    {
      request: {
        query: LATEST_SELL_SIGNALS,
      },
      result: {
        data: {
          yourData: { name: 'Storybook Data' },
        },
      },
    },
  ]
  
  
  export default {
    title: 'Sales Components'
  }
  
  export const latest_sells = () =&gt; {
    return (
        &lt;MockedProvider mocks={mocks}&gt;
          &lt;LatestSells /&gt;
        &lt;/MockedProvider&gt;
    )
  }
  </code></pre>
  
  <p>Where the LATEST_SELL_SIGNALS is this file:</p>
  
  <pre><code>import { gql } from 'apollo-boost'
  
  export const LATEST_SELL_SIGNALS = gql`
    query {
      latestSellSignalsList(orderBy: createdAt_DESC, first: 10) {
        items {
          name
          ticker
          boughtAt
          soldAt
        }
      }
    }
  `
  </code></pre>
  
  <p>the Component I'm wrapping is using react hooks like this:</p>
  
  <p><code>const { loading, error, data } = useQuery(LATEST_SELL_SIGNALS)</code></p>
  
  <p>The import for the query is the same in the Component as it is in the mock</p>
  
  <p>please note this all works just fine with my normal Apollo Provider, I'm only having issues with the MockProvider not doing it's thing.</p>
  
  <p>The component. also renders fine</p>
