Fix SecurityStyleChangedObserverNonsecureConnection test

This test originally tried to use a net::URLRequestMockHTTPJob subclass
(URLRequestNonsecureConnection) to mock a connection with obsolete TLS
settings, but due to some missing boilerplate,
URLRequestNonsecureConnections were never actually used, and the test
was rather nonsensical. URLRequestNonsecureConnection was removed as
dead code in https://codereview.chromium.org/1899003002/.

This CL adds URLRequestNonsecureConnection back in and adds the missing
boilerplate so that this class is actually used. The test now
meaningfully tests what it's supposed to test.
