Renamed controls creating duplicate curves in sequencer that once fixed up cause selection issues.

When a control is renamed after it has already been animated in a sequence, the control curve name map needs to be fixed up. Once it is fixed, selecting the control in the world will not map the selection to the sequencer correctly.

• Create a control rig
• Use it in an animation.
• Rename a control and add a new control with the old control's name in the hierarchy
• Open animation.
• Get error message: "Duplicate corrupted controls found in level sequence"
• Select new control.
• Note selection is wrong in sequencer track view.
