[webauthn] NULL or DOMException

AngeloKai has just created a new issue for https://github.com/w3c/webauthn:

== NULL or DOMException ==
The last step of both the Create and Get API specifies that we return NotAllowedError if it fails. But the credential management spec specifies that [the two APIs return a Credential if one can be returned given the options provided, null if no credential is available, or an error if discovery fails (for example, incorrect options could produce a TypeError).](https://www.w3.org/TR/credential-management-1/#credential-internal-methods). We should figure out what case would make us return null.
