testIntFire is not protected by DO_UNIT_TEST macro
Created by: subhacom
In file benchmark/benchmark.cpp
functions are not always enabled. While the declaration of function (e.g. testIntFireNetwork) used in this file are enabled/disabled by DO_UNIT_TEST macro.
This is breaking the MOOSE build on launchpad where DO_UNIT_TEST is not defined.
