Subject: [RFC/PATCH 06/12] mktag tests: improve verify_object() test coverage

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Thu, 26 Nov 2020 02:28:48 +0100

The verify_object() function in "mktag.c" is tasked with ensuring that
our tag refers to a valid object. The existing test for this might
fail because it was also testing that "type taggg" didn't refer to a
valid object type (it should be "type tag").

Let's split these tests up, so we're testing all combinations of a
non-existing object and in invalid "type" line.
