Unfreeze of duplicated track removes routing (FIXED)

[Mage]

Platform: macOS, current Reaper.

Steps to reproduce:

1. Create a track
2. Create another track and nest it in the first track
3. Put a random instrument on the nested track, and draw a few midi notes (to make freeze work)
4. Freeze the nested track
5. Freeze the parent track
6. Duplicate the parent track (right-click, duplicate tracks)
7. Unfreeze the original parent track
8. Unfreeze the duplicated parent track

Expected result:

The original nested track is routed to the original parent track. The duplicated nested track is routed to the duplicate of the original parent track via "Route / Parent send (Track 3)"

Actual result:

The original nested track is routed to the original parent track. The duplicate of the nested track is routed to nowhere. You need to open the Route window and check the Parent send checkbox to fix it.
