Fix iPhone 16e restore from normal mode

Because of the new Apple baseband the initial TSS request won't succeed
when restoring from normal mode due to missing data for a @bbticket.
So now if the baseband information is missing, we don't try to add BBTicket
data at all, which will make it work for iPhone 16e devices.
