tests: Stop referring to server ports when they're not used

Several tests referred to specific server ports even when the test
didn't actually use that server or specify that it's needed. In such
cases, the test harness substitutes the text "[not running]" as the port
number which causes many such tests to fail due to the inability to
parse the URL.  These tests are changed to use %NOLISTENPORT which will
always be substituted correctly.
