The previous problem of the framework not properly restarting after accepting
the password to decrypt the storage is also a problem when restarting the
framework to display the encryption progress screen.  So like the previous
hacky fix, add a sleep to wait a few moments before proceeding.  Also,
increase the sleep of the previous fix from 1 second to 2, as the problem
was seen once more in testing.  A proper fix has been designed and hopefully
will work and be checked-in RSN.
