[MOB-739] Update ChipDNA to properly reference receipt data

Ticket MOB-739

iOS SDK 2.0.0 | ChipDNA | Customer name for Apple Pay transaction is still "SWIPE CUSTOMER"

ChipDnaDriver was looking for the transactionSource using the wrong, hardcoded receipt field. I made it so that it uses a variable that ChipDNA has that references the transactionSource
Changed 'Contactless Customer' to 'Mobile Device Customer'
