mktag tests: test for-each-ref

Add a "for-each-ref" for all the mktag tests. This test would have caught the segfault which was fixed in c6854508808 (ref-filter: fix NULL check for parse object failure, 2021-04-01). Let's make sure we test that code more exhaustively. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
