[PATCH] helper/test-ref-store: fix "new-sha1" vs "old-sha1" typo

[Christian Couder]

It looks like it is a copy-paste error  made in 80f2a6097c
(t/helper: add test-ref-store to test ref-store functions,
2017-03-26) to pass "old-sha1" instead of "new-sha1" to
notnull() when we get the new sha1 argument from
const char **argv.
