Fix missing objects if they where deltified using ref-delta

- Deleted invalid logic that returned nil if an ref-delta was not found into the decoder index. This logic was missing objects if it was deltified using ref-deltas.
- Now, to avoid that problem, index is mandatory to decode correctly a packfile of a specific type. Decoder.SetOffsets method now is called into the EncodedObjectIterator to avoid this problem.
