Title: Fix for 18666

The issue was that we weren't checking for _get_tracker_for_path returning
None in file_finished.

Decided that that whole system was not well designed and made
_get_tracker_for_path pass on its KeyErrors instead.

Made trackers be a defaultdict instead of having to manually specify which
file types to create keys for. This seems safer.
