title: Unable to finish unfinished transactions in payment queue
body: <p>My application went to some odd state in IAP sandbox... Every time I launch application it is asking for password of particular test user. I guess due to unfinished transaction. I really want to finish that transaction, but it's not possible. Some background info and what I have done for it:</p>
  
  <ul>
  <li>I've deleted that test user from itunesconnect</li>
  <li>As soon as application launches I call <code>[[SKPaymentQueue defaultQueue] addTransactionObserver:self]</code></li>
  <li>No payment queue update notification is received after I enter password for that particular test user, or hit cancel</li>
  <li><code>[SKPaymentQueue defaultQueue].transactions.count</code> is always <code>0</code>, so I can't manually finish unfinished transactions</li>
  <li>I've delete app from device, restarted device - still asking for password</li>
  <li>I am logging out of user from Settings -> iTunes &amp; App Store</li>
  <li>After I cancel dialog box asking for password, somehow I am able to login with another test user, but next time I am still getting dialog box for password of old test user.</li>
  </ul>
  
  <p>The only thing is left to change bundle id, which is not desirable in my case. Hopefully someone knows alternative ways how to get rid of unfinished transaction.</p>
