Subject: [PATCH v2 2/4] test: refactor create_commits_in() for t5411 and t5548

From: Jiang Xin <[email-masked]>
Date: Sat, 12 Jun 2021 13:07:09 +0800

From: Jiang Xin <[email-masked]>

Use "test_commit" in "create_commits_in" to create commit and get abbrev
object ID by using function "get_abbrev_oid".
