When creating the sparse-checkout file, Git does not create the leading directory, "$GIT_DIR/info", if it does not exist. This causes problems if the repository does not have that directory. Therefore, ensure that the leading directory is created. This is the only "open" in builtin/sparse-checkout.c that does not have a leading directory check. (The other one in write_patterns_and_update() does.) Note that the test needs to explicitly specify a template when running "git init" because the default template used in the tests has the "info/" directory included.
