HPCC-12999 HTTPCALL error

Although technically allowed by HTTP 1.1 specification, appending the
default port to an HTTPCALL causes a failure in some services. Specifically
the one in our HTTPCALL documentation
 api.worldbank.org:80
This fix ensures HTTPCALL will not append the port if its the default 80.
