NFD

The way to reproduce:

(start nfd on nodes A & B)

$ build/bin/nfdc create udp://192.168.1.2
$ build/bin/nfdc create tcp://192.168.1.2
$ build/bin/nfdc add-nexthop ndn:/test-nfdc 7  10
$ build/bin/nfdc add-nexthop ndn:/test-nfdc 13 10
$ build/bin/nfdc set-strategy ndn:/ ndn:/localhost/nfd/strategy/broadcast
$ /ndn-tlv-ping/build/ndnping ndn:/test-nfdc -c 20

nfd: ../daemon/table/strategy-choice.cpp:172: nfd::fw::Strategy& nfd::StrategyChoice::findEffectiveStrategy(const nfd::pit::Entry&) const: Assertion `static_cast<bool>(nameTreeEntry)' failed.

IMPORTANT:
Doesn't happen when the prefix points to a single face (only a tcp4 face or a udp4 face). I was able to reproduce this bug only when I had more than one face attached to the prefix.
