title: Unable to download files from firebase through pyrebase
body: <p>I am stuck with it for a long time now, must be something silly!!!</p>
  
  <p>I have this simple code that uses pyrebase to connect to Firebase:</p>
  
  <pre><code>db = firebase.database()
  auth = firebase.auth()
  storage = firebase.storage()
  user = auth.sign_in_with_email_and_password('user','pwd')
  
  tok = user['idToken']
  
  try:
      files = db.child("files").get(tok)
      l = []
      for f in files.each():
          l = f.val()
          print(l)
          storage.child(l).download(l,token=tok)
          # url = storage.child(l).get_url(tok)  -----This line gets the proper URL
  except Exception as e:
      print(e)
  </code></pre>
  
  <p>I am getting data correctly accessed from DB, but the download task does nothing. I have no idea what I am doing wrong here.</p>
  
  <p>Thanks in advance!</p>
  
  <p><strong>EDIT 1:</strong>
  as per suggestion:</p>
  
  <p>Database structure:</p>
  
  <pre><code>{
    "files" : {
      "-L2vvsSL3l95QZqMILRb" : "car_WIFI_6cf4d4f1-4bfe-488b-b671-d0f816cd5e65.txt",
      "-L2vvsSScNqiUZ-HYTM1" : "car_GPS_6cf4d4f1-4bfe-488b-b671-d0f816cd5e65.txt"
    }
  }
  </code></pre>
  
  <p>And storage structure:</p>
