title: send_reset_password_instructions not changing token
body: <p><code>u.send_reset_password_instructions</code> sends a url to</p>
  
  <p><code>/users/password/edit?reset_password_token=zybhayhwh</code> (edited for SO)</p>
  
  <p>but this token is always the same, no matter how many times I reset my password or call u.send_reset_password_instructions</p>
  
  <p>Incidentally, when I'm taken to the reset page I get redirected to the home page immediately.. probably because the cookie has the old token.</p>
  
  <p>Why is my token not changing?</p>
