CREDENTIAL: Serialize 'PasswordCredential' objects with "" as the federation.

After https://codereview.chromium.org/1723583004, we serialize
`PasswordCredential` objects with a `federation_url` of "null" (as "null" is
the serialization of an empty/unique origin.

Neither Android nor Vasilii like this. This patch special-cases things to
ensure that Android (and Vasilii) remains as happy as can be.
