code error in generate canditates when update

[laisimiao]

In line168 of run_tracker.py, but I think it should be:
neg_examples = neg_generator(target_bbox, opts['n_neg_update'], opts['overlap_neg_update'])
rather than:
neg_examples = neg_generator(target_bbox, opts['n_neg_update'], opts['overlap_neg_init'])
