Jeff King 09b2aa30c9 t1416: avoid hard-coded sha1 ids
The test added by e5256c82e5 (refs: fix interleaving hook calls with
reference-transaction hook, 2020-08-07) uses hard-coded sha1 object ids
in its expected output. This causes it to fail when run with
GIT_TEST_DEFAULT_HASH=sha256.

Let's make use of the oid variables we define earlier, as the rest of
the nearby tests do.
