[PATCH v2 0/1] remove unnecessary if statement

In an earlier patch[1] (1a764cdbdc (Merge branch 'ua/some-builtins-wo-the-repository', 2025-03-26)) which has been merged to the master, we checked `repo` is not NULL before making call to `repo_config()`. Later, in another patch series[2] which has been merged to master, `repo_config()` was taught to allow `repo` to be NULL.

So there is not need for checking if the `repo` is NULL before calling repo_config() in the earlier patch.

Also, Patrick suggested having the test inside the "t1517-outside-repo.sh"[3] instead of having it in the individual test files like[2] and I also think it is a good approach as we will have all such tests in one place. So, for this patch, I added the test inside the "t1517-outside-repo.sh". If this is accepted, I will move the test for previous builtin cmd which has already been merged to master to "t1517-outside-repo.sh" file.
