[Autofill] Fix heuristics to detect consecutive CVCs.

Added a check after parsing a cvc. If it's the only type parsed so far, check the previous field. If it's also a cvc, just label the current field as a cvc without looking at the next fields. This also fixes some cases where we would label some names as cc-names.
