Re: [webauthn] Fix #720: Don't return user handle in 2nd factor mode

I now agree that the user handle is not private information, but I don't see how the RP could not know the user's identity if the RP has already looked up a list of credential IDs for that user.

Either way, I see now that [CTAP's getAssertion method](https://fidoalliance.org/specs/fido-v2.0-rd-20170927/fido-client-to-authenticator-protocol-v2.0-rd-20170927.html#authenticatorGetAssertion) always returns the `user.id` even in the 2nd factor case, so I support closing this. Sorry for wasting everyone's time on yesterday's call.
