Specifying YKFKeyFIDO2GetAssertionRequestOptionUV results in failure 100% of the time

[Brandon-T]

Steps to Reproduce:

1. Add a YubiKey to Github account in settings -> security.

2. Sign out of github.

3. Go to the login page and enter credentions and hit log in.

4. Tap "Use Security Key"

5. a. If we send (login will fail):

assertionRequest.options = [
    YKFKeyFIDO2GetAssertionRequestOptionUP: true,
    YKFKeyFIDO2GetAssertionRequestOptionUV: false
 ]

5. b. If we send (login will fail):

   assertionRequest.options = [
   YKFKeyFIDO2GetAssertionRequestOptionUP: true,
   YKFKeyFIDO2GetAssertionRequestOptionUV: true
   ]

6. c. If we send (login will succeed):

assertionRequest.options = [
    YKFKeyFIDO2GetAssertionRequestOptionUP: true
]

Notice that in 5.c. the YKFKeyFIDO2GetAssertionRequestOptionUV option was removed.. However, documentation for this option says the default value is false so 5.a. should have worked..

    The options provide a list of properties to influence authenticator operation when signing, as specified
    in in the table below. This parameter is optional.

    @code
    Key           | Default value      | Definition
    ----------------------------------------------------------------------------------------
    uv            | false              | user verification: Instructs the authenticator to
                                         require a gesture that verifies the user to complete
                                         the request. Examples of such gestures are fingerprint
                                         scan or a PIN.
    ----------------------------------------------------------------------------------------
    up            | true               | user presence: Instructs the authenticator to require
                                         user consent to complete the operation.
