[ndnSIM] meaning of HopCounts -1 in application level traces

[Pawan Subedi]

Dear ndnSim team,

Sorry to bother with the last email. I think I have figured out the real
cause of the problem. I had actually set the producer application and the
consumer application for the similar name prefix in the same node for some
nodes while selecting nodes randomly.

Thank you!

Sincerely,
Pawan Subedi
