title: Unable to create token with rtweet package
body: <p>I am not able to create a twitter token using create_token from rtweet package:</p>
  
  <pre><code>library (rtweet)
  twitter_token &lt;- create_token(app = appname, # as set in Twitter API
                                consumer_key = key, # as set in Twitter API
                                consumer_secret = secret) # as set in Twitter API
  </code></pre>
  
  <p>The output I get is:</p>
  
  <pre><code>Error in init_oauth1.0(self$endpoint, self$app, permission = self$params$permission,  : 
    Forbidden (HTTP 403).
  </code></pre>
  
  <p>I followed the instructions to setup Twitter API as disclosed in <a href="http://rtweet.info/articles/auth.html" rel="nofollow noreferrer">http://rtweet.info/articles/auth.html</a>, and triple checked that the Callback URL was properly set as <a href="http://127.0.0.1:1410" rel="nofollow noreferrer">http://127.0.0.1:1410</a>. </p>
  
  <p>I also tried:</p>
  
  <pre><code>createTokenNoBrowser&lt;- function(appName, consumerKey, consumerSecret, 
                                  accessToken, accessTokenSecret) {
    app &lt;- httr::oauth_app(appName, consumerKey, consumerSecret)
    params &lt;- list(as_header = TRUE)
    credentials &lt;- list(oauth_token = accessToken, 
                        oauth_token_secret = accessTokenSecret)
    token &lt;- httr::Token1.0$new(endpoint = NULL, params = params, 
                                app = app, credentials = credentials)
    return(token)
  }
  </code></pre>
  
  <p>It seems to work, but when I call</p>
  
  <pre><code>rt &lt;- stream_tweets(q = q, file_name = filename,token = twitter_token)
  </code></pre>
  
  <p>I get: <code>Error: Not a valid access token.</code></p>
  
  <p>What might be going wrong?
  I am currently using R 3.5.0. Thank you.</p>
