Damien Robert 796d61cdc0 midx.c: fix an integer underflow ... When verifying a midx index with 0 objects, the m->num_objects - 1 underflows and wraps around to 4294967295. Fix this both by checking that the midx contains at least one oid, and also that we don't write any midx when there is no packfiles. Update the tests to check that `git multi-pack-index write` does not write an midx when there is no objects, and another to check that `git multi-pack-index verify` warns when it verifies an midx with no objects. For this last test, use t5319/no-objects.midx which was generated by an older version of git.
