Incorrect use of iterator, lead to error when slice on candidates.

I use 'Coll' instead of 'CollsWithQVecs'.

Why does the grouping not work directly with the iterator?

The grouping is working well with the iterator.
The issues is I slice the candidate again while the candidate already sliced (line 2351, 2321).

And we don't want to slice the tracks by the collision, so we have to abandon the iterator.
