Local fix

Problem summary

• Trivial Merge Results in NullPointerException in UCM.
  
  The compare merge uses the wrong feature id for the proxy
  object that causes bad matching id generated for the
  add/delete deltas.
  

Problem conclusion

• Fixed in release RSx 753.
  
  Uses the proxy object container?s Meta class to obtain the
  proper feature id.
  

Temporary fix
