Additional reconnect improvements. Made sure that payment page is not displayed
twice if we have previously received payment notification.

BUG=chromium-os:10075, chromium-os:10428
TEST=tough one to test - requires OTA-SP activation of number of devices until reproduces. we should make sure that we 1) don't get stuck in 'Conneting...' phase after payment and 2) we never see the payment portal twice for the same device once the payment is processed.
