Separate testing of FidoRequestHandler

Create separate unit test to separate logic of FidoRequestHandler and
MakeCredentialHandler. Unit test for FidoRequestHandler should only test
two things.
  1) At most one response from multiple authenticators should be passed
     to the relying party.
  2) Second, cancel operation should be invoked to authenticators that
     error out.
