[FIX] Return proper status code for unsupported UserToken types

 - Test case Err-009.js in Session services/Session base in CTT fails
   due to matching of userToken types against configured endpoints
 - The error status code to be returned is BadIdentityTokenInvalid
   (0x80200000) but obtained BadIdentityTokenRejected (0x80210000)
 - This fix will resolve the test and returns the expected status code
   (BadIdentityTokenInvalid - 0x80200000)
