Several fixes in forwarding strategies and NACK processing

- All strategies will forward to one green face first, if it exists
- Implemented logic to detect retransmitted interests (same face)
- If interest is retransmitted and all faces are exhausted during the
  propagation face, increase max retx counter and try again
- PIT entry lifetime is updated on every non-duplicate interest reception
