On the '1.3.x-r1804008-group' branch: Fix a couple of responses with
chunked encoding in the test suite that are ill-formed per RFC7230,
and now result in an error.

On trunk, these tests use MockHTTP framework and that results in properly
parseable responses, but on the 1.3.x branch they were hand-crafted.
I think that the trunk equivalents of all these responses are just empty
"Transfer-Encoding: chunked" responses, so I changed them here accordingly.

* test/test_auth.c
  (test_authentication_disabled, test_unsupported_authentication,
   basic_authentication, digest_authentication, authentication_switch_realms):
   Mock empty chunked responses.

* test/test_context.c
  (test_ssltunnel_no_creds_cb, ssltunnel_basic_auth,
   test_ssltunnel_digest_auth): Mock empty chunked responses.
