t5703: run all non-httpd-specific tests before sourcing 'lib-httpd.sh'

't5703-upload-pack-ref-in-want.sh' sources 'lib-httpd.sh' near the end
to run a couple of httpd-specific tests, but 'lib-httpd.sh' skips all
the rest of the test script if the dependencies for running httpd
tests are not fulfilled.  However, the last six tests in 't5703' are
not httpd-specific, but they are skipped as well when httpd tests
can't be run.

Move these six tests earlier in the test script, before 'lib-httpd.sh'
is sourced, so they will be run even when httpd tests aren't.  Note
that this is not merely a pure code movement, because the setup test
case for the httpd tests needed an additional 'rm -rf
"$LOCAL_PRISTINE"' to clean up a directory left behind by the moved
non-httpd-specific tests.

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.
