title: Remove/delete child only
body: <p>In Python 3.5 I scrape data from the internet and using Pyrebase 3.0.27 library to perform a CRUD operation for my Firebase database. The update and get method of Pyrebase works well except the remove.</p>
  
  <p>I have a Firebase structure like this</p>
  
  <pre>mycustomapp-51146
     -CebuPacific
        -db_fare
            +1
            +2
            +3
            +4
  </pre> 
  
  <p>When executing this method:</p>
  
  <pre><code>self._fb_database.child('CebuPacific').child('db_fare').remove(self._fb_token)
  </code></pre>
  
  <p>This will be the result:</p>
  
  <pre>
  mycustomapp-51146
  </pre>
  
  <p>But this is the result I wish to achieve:</p>
  
  <pre>
  mycustomapp-51146
     -CebuPacific
  </pre>
