U2F devices, like the Yubikey4, fail in a slightly unexpected way when assertions set UP=false. Handle this edge case and also make sure that failures when checking for excluded credentials won't break the entire ceremony. Similar to #15975, but in the registration flow this time. Repro steps: 1. Register a Yubikey 4 2. Attempt to register a different security key 3. Registration fails with a "user presence required" error
