Message-ID: <patch-5.6-f4c41be92d-20210617T104011Z-avarab@gmail.com>

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.
