  Add unit tests for object write-back Basic write-back & in-memory editing for objects is now tested in t0403 (commits), t0802 (tags) and t0902 (trees). Add new helper functions in test_helpers.c to remove the loose objects created when doing write-back tests. Signed-off-by: Vicent Marti <tanoku@gmail.com>
