We are basically failing here https://searchfox.org/mozilla-mobile/source/android-components/components/concept/storage/src/main/java/mozilla/components/concept/storage/CreditCardsAddressesStorage.kt#266-267 because the user could have either the expiry month or year not filled in and then submitting the form which will prompt the save credit card dialog.

I think we should just return an empty string if either of those fields are missing.
