title: Default query params not getting passed in axios request
body: <p>I'm using axios.create() to pass in a baseURL and some default query params like this </p>
  
  <pre><code>axios.create({
      baseURL: 'http://somebigurlhere',
      params: {
          part: 'part',
          maxResults: 5,
          key: 'key'
     }
  });
  </code></pre>
  
  <p>When I use </p>
  
  <pre><code>axios.get('/search', {
      params: {
          q: 'word'
      }
  });
  </code></pre>
  
  <p>the default params do not get merged in the GET call.</p>
  
  <p>What I get is 
  <code>http://somebigurlhere/search?q=word</code></p>
  
  <p>instead of
  <code>http://somebigurlhere/search?part=part&amp;maxResults=5&amp;key=key&amp;q=asd</code></p>
  
  <p>I tried putting the configuration in many other ways but it still doesn't work.
  Am i doing something wrong here ?</p>
  
  <p>I tried the same in other projects and it is working there. Just created a new react app with create-react-app and this doesn't seem to work anymore.</p>
