Build fails when build host running web server

If the host on which the policy engine is running a web server that
respoonds with a HTTP response on the URL "http://localhost", the build
fails because one of the tests in ONAP-XACML expects a ConnectException
on this URL. When the URL returns a valid respose the test fails causing
the buld to fail.

This fix changes the URL to "http://localhost:54287", which I guess could
also exist but is much less liekly to exist.
