Fix FormParserTest.CVC

The test was meant to check what happens if a password field has a
CVC-like name. Instead, it tested what happens if a text field has
this name.

This CL fixes that mistake. The test thankfully still passes.

This is a yak-shaving for adding the fallback pass, hence the below
bug association.
