object tracing: Fix the issue that objects lost from trace list

Browse source 
Add a flag for identifing whether this object is on the trace
list. Ensure that link any object to the trace list only one time.
It will avoid the issue about lost object caused by adding a
object to trace list twice.

Fixes #19537
