esipa: supply eimTransactionId in profileDownloadTriggerRequest
When we supply an eimTransactionId in profileDownloadTriggerRequest,
the IPAd will echo the same eimTransactionId in the
initiateAuthenticationRequestEsipa message. This allows the eIM
to distinguish to which transaction (work) the received
initiateAuthenticationRequestEsipa belongs. This was not possible
before. The eIM had to rely soly on the PID of the sub process
which is handling the HTTP connection.
