Fix tracking evaluation

[sfmig]

Rebase after #242

• Fixes mismatch between indexing ground truth and predictions.
• Extends tests so that the tracking output is compared directly to the expected files (i.e., true positives, Missed detections, false negatives, id switches and MOTA per frame must match)
• Changes the name of the tracking metrics output csv file to include name of the input video.
