GetExecutionSummaryStatus not working due to special ASCII characters in message ID

[christophewyns]

When calling the GetExecutionSummaryStatus with a message ID containing a special ASCII character like "DC3" (coming from the executing ID generated by D365FO), the value "DC3" is not sent in the request (the execution id/messages id is sent without this part), we can see it in the network.log file when enabling the System.Net logging option in the file RecurringIntegrationsScheduler.Server.exe.config.
