[FIX] Check the request type for not activated sessions

 - Currently when the session is not activated and if close Session
   is requested, the server will return a Bad_SessionNotActivated
   status code
 - In new CTT, this will cause the issue in various conformance units
   such as Security Username Password and session base
 - So modified the SessionNotActivated check to ignore if the request
   is of type CloseSessionRequest
