title: FileTransfer is not defined in ionic 1.3.2
body: <p>I know this issue has already been debated here and on the ionic forum but I can't solve the following issue :</p>
  
  <pre><code>ReferenceError: FileTransfer is not defined
  </code></pre>
  
  <p>I'm using the last version of ionic : 1.3.2 and cordova version 4.2.0
  I added both file and file-transfer plugins using the following commands:</p>
  
  <pre><code>ionic plugin add org.apache.cordova.file-transfer
  ionic plugin add org.apache.cordova.file
  </code></pre>
  
  <p>and I, of course, built the project using </p>
  
  <pre><code>ionic build
  </code></pre>
  
  <p>but I still can't manage to make this work even with a sample code.
  Each time I access the plugin I get this error.
  I tried to start multiple other new projects without any success.</p>
  
  <p>Do you have any solution to that problem ?</p>
