Local fix

Problem summary

• USERS AFFECTED:
  Some customers use third party cookie and it can be expected to
  be null sometime and commerce code should handle this situation
  in this particular class
  
  PROBLEM ABSTRACT:
  Null Pointer Exception being thrown when cookie.getValue() is
  null and being passed into URLDecoder in
  RuntimeServletFilter.class
  
  BUSINESS IMPACT:
  Customer is not able to turn on trace because
  RuntimeServletFilter.class will throw null pointer exception
  when cookie is null
  
  RECOMMENDATION:
  

Problem conclusion

• The NPE should be handled in our code, and if cookie value is
  null, it should be printed as "cookie is null" instead of
  throwing NPE.
