Convert tests that use `test_path_is_file` and `test_path_is_missing` to instead use a set of helpers `test_ref_exists` and `test_ref_missing`. These helpers are implemented via the newly introduced `git show-ref --exists` command. Thus, we can avoid intimate knowledge of how the ref backend stores references on disk.
