Extract Iteration from log instead of computing it from parameters

[sguada]

Removed parameters [init_iter=0] [test_interval=1000]
Not needed anymore, now it extracts that info from the log

Why not just print the iter_ in Solver::Test()?

for (int i = 0; i < test_score.size(); ++i) {
LOG(INFO) << "Iteration " << iter_ << ", Test score #" << i << ": "
<< test_score[i] / param_.test_iter();
}

grep -B 2 'Test ' $1 > aux.txt

The above line extracts the test iteration.

@chyojn, you are right! Test iteration might not be equal to the printed training iteration. I'll fix it.
