title: DraftJS editor create from HTML is not working
body: <p>The editor is starting as if it has empty string!</p>
  
  <p>I tried this:</p>
  
  <pre><code>EditorState.createWithContent(ContentState.createFromText('Hello'))
  </code></pre>
  
  <p>and this: </p>
  
  <pre><code>const html = '&lt;p&gt;Hey this &lt;strong&gt;editor&lt;/strong&gt; rocks &lt;/p&gt;';
  const contentBlock = htmlToDraft(html);
  if (contentBlock) {
    const contentState = ContentState.createFromBlockArray(contentBlock.contentBlocks);
    const editorState = EditorState.createWithContent(contentState);
    this.state = {
      editorState,
    };
  }
  </code></pre>
  
  <p>and this:</p>
  
  <pre><code>import htmlToDraft from 'html-to-draftjs'
  htmlToDraft(text)
  </code></pre>
  
  <p>nothing worked!</p>
