title: iOS in app purchase receipt with different itunes user
body: <p>I am using receipt validation locally on device and targeting iOS 7+</p>
  
  <p>I am testing auto renew subscription in app purchase in the sandbox environment and I noticed this scenario.</p>
  
  <p>-User A is signed in iTunes account on device, purchases subscription in app, gets app receipt.
  -User A signs out iTunes account on device and User B signs in
  -User B launches app
  -User B will continue using User A’s subscription because [[NSBundle mainBundle] appStoreReceiptURL] is valid and will return User A's receipt.</p>
  
  <p>How come it doesn't return User B's receipt?</p>
