Protect confirmed tracking from evaluation overwrites

Prevent TrackComboPointCast from overwriting confirmed tracking with
unconfirmed evaluation data. Once DoCast confirms a cast, subsequent
macro evaluations will no longer overwrite the tracking entry.

This fixes the issue where pfUI's second AddEffect call would see
unconfirmed tracking because evaluations overwrote the confirmed data.
