Track group renames don't enter the Undo history. Undoing and redoing often loses name changes.

Repro:
# Create a timeline. (Assets -> Create -> Timeline)
# Open the timeline by double clicking in project view.
# Create an track. (+ -> Any track type)
# Create a track group. (+ -> Track group)
# Pull the track created in Step 3 into this group, so that it is nested under the group name.
# Rename your track group.
# Undo - track group name reverts.
# Redo

*Expected:* Track group name redone to name set in step 6.

*Actual:* Track group name stays the same.
