NLSR

In NLSR logs it is observed that NLSR tries to set strategies for the same prefixes multiple times.

NLSR calls setStrategies first time in: https://github.com/named-data/NLSR/blob/fad8e257c054d2c0eca6a9e1a7635dbee34902ed/src/nlsr.cpp#L196

NLSR then also calls it in: https://github.com/named-data/NLSR/blob/fad8e257c054d2c0eca6a9e1a7635dbee34902ed/src/hello-protocol.cpp#L237
Looks like this line should not be there.
