[PATCH v2 0/3] t1301: various updates

[Jiang Xin <worldhello.net@gmail.com>]

From: Jiang Xin <zhiyou.jx@alibaba-inc.com>

## Changes since v1

The first version is based on the "master" branch, and this v2
revsion is based on the "maint" branch. Because only master
branch has the commit 93e02b6e1e (tests: don't assume a .git/info
for .git/info/grafts, 2022-06-03), we need add a "-p" option for
mkdir in patch 3/3.

It's very interesting. Just because the "mkdir .git/info" changes
in the above commit conflicts with our internal reference-transaction
hook which will automatically create a ".git/info" directory to
create some files inside, I found the wrong template issue in t1301
which is fixed in patch 1/3.

Other changes see the following range-diff.

    +    Refactor several test cases to use "test_when_finished" for cleanup.
    +
    +    1. For first of these, we used to clean-up outside the test, but instead
    +       let's use test_when_finished for that.
    +
    +    2. For the second, we used to leave "new" after we are done, but not use
    +       it at all later. Now we do clean up.
    +
    +    3. For the rest, these child.git test repositories used to follow
    +       "initialize what we are going to use to a known state before we use"
    +       pattern, which is not wrong per-se, but now we use "clean up the
    +       cruft we made after we are done" pattern, which may arguably be
    +       better simply because the test that makes cruft should know what
    +       cruft it created better than whatever comes later that may not know.

    -    Since the test case "shared=all" and all subsequent will work properly
    -    in the default test repository, we don't need to create and change to
    -    the "sub" directory in the test case "shared=all".
    +    Besides, all subsequent test cases assuming they are in the "sub"
    +    directory do not run any destructive operations in their parent
    +    directory (".."), and will not make damage out side of $TRASH_DIRECTORY.
     
    +    So it is a safe change for us to run the test case "shared=all" in
    +    current repository instead of creating and changing to "sub".
    +
    +    For the next test case, we no longer run it in the "sub" repository
    +    which is initialized from an empty template, we should not assume the
    +    path ".git/info" is missing. So add option "-p" to mkdir.
