Reviewed by Brent Fulgham.

Previously, we would error out a request if we couldn't satisfy a given
attestation type for our platform authenticator. However, after our platform
authenticator stopped supporting attestation, we changed the behavior to
return a none attestation, but omitted the step of deleting any duplicate
credentials with the same user handle. This patch fixes that by deleting
the potential duplicate credential.
