title: Flask-User auto login issue
body: <p>I don't have much experience with Flask and Flask-User so bear with me. On my app, I want to implement these two features:</p>
  
  <ol>
  <li>auto-login after registration</li>
  <li>email verification (the user should be able to log in without verifying)</li>
  </ol>
  
  <p>It seems to me that enabling these three options in my config should do the trick:</p>
  
  <pre><code>    USER_ENABLE_LOGIN_WITHOUT_CONFIRM_EMAIL = True,
      USER_ENABLE_CONFIRM_EMAIL=True,
      USER_AUTO_LOGIN_AFTER_REGISTER=True,
  </code></pre>
  
  <p>but with these settings on, auto-login doesn't work.
  Later, I read <a href="https://github.com/lingthio/Flask-User/issues/31" rel="nofollow noreferrer">here</a> that setting <code>USER_ENABLE_CONFIRM_EMAIL=False</code> will fix the issue. So I tried these settings:</p>
  
  <pre><code>    USER_ENABLE_LOGIN_WITHOUT_CONFIRM_EMAIL = True,
      USER_ENABLE_CONFIRM_EMAIL=False,
      USER_AUTO_LOGIN_AFTER_REGISTER=True,
  </code></pre>
  
  <p>Now, auto-login DOES work but email confirmation does not. When I use <code>url_for('user.resend_confirm_email')</code>, I get this error:</p>
  
  <pre><code>werkzeug.routing.BuildError: Could not build url for endpoint 'user.resend_confirm_email'. Did you mean 'user.profile' instead?
  </code></pre>
  
  <p>I think there is a problem with my config settings. Help is appreciated.</p>
