t5510-fetch: run non-httpd-specific test before sourcing 'lib-httpd.sh'
't5510-fetch.sh' sources 'lib-httpd.sh' near the end to run a httpd-specific test, but 'lib-httpd.sh' skips all the rest of the test script if the dependencies for running httpd tests are not fulfilled. Alas, recently cdbd70c437 (fetch: add --[no-]show-forced-updates argument, 2019-06-18) appended a non-httpd-specific test at the end, and this test is then skipped as well when httpd tests can't be run. Move this new test earlier in the test script, before 'lib-httpd.sh' is sourced, so it will be run even when httpd tests aren't. Also add a comment at the end of this test script to warn against adding non-httpd-specific tests at the end, in the hope that it will help prevent similar issues in the future.
