[Bug]: RequestTransactionManager does not contain a transaction in runningRequests when endRequest is called

### What happened?

When I try to run the following simple test with Plc4xServer, an IllegalArgumentException is thrown and displayed in the log due to an empty ConcurrentHashMap of runningRequests in the RequestTransactionManager.
Apart from the exception that is displayed in the log, the test runs successfully.

It seems that the transaction was not previously added to the runningRequests.

My test code:
```
import static org.assertj.core.api.Assertions.assertThat;
import org.apache.plc4x.java.DefaultPlcDriverManager;
import org.apache.plc4x.java.api.PlcConnection;
import org.apache.plc4x.java.api.PlcConnectionManager;
import org.apache.plc4x.java.api.messages.PlcWriteRequest;
import org.apache.plc4x.java.api.messages.PlcWriteResponse;
import org.apache.plc4x.java.api.types.PlcResponseCode;
import org.apache.plc4x.java.tools.plc4xserver.Plc4xServer;
import org.junit.jupiter.api.Test;

public class BasicTest {

@Test
void basicPlc4xServerTest() throws Exception {
Plc4xServer plc4xServer = new Plc4xServer();
plc4xServer.start();

String connectionStringTemplate = "plc4x://localhost:%d?remote-connection-string=%s";
String connectionStringSimulatedTemplate = "simulated%3A%2F%2Flocalhost";
String connectionUrl = String.format(connectionStringTemplate, plc4xServer.getPort(), connectionStringSimulatedTemplate);

PlcConnectionManager connectionManager = new DefaultPlcDriverManager().getConnectionManager();
final PlcWriteResponse response;
try (PlcConnection connection = connectionManager.getConnection(connectionUrl)) {
final PlcWriteRequest request = connection.writeRequestBuilder().addTagAddress("foo", "STATE/foo:DINT", 42).build();
response = request.execute().get();
}
assertThat(response.getResponseCode("foo")).isEqualTo(PlcResponseCode.OK);
}

}
```

The log output.
```

Start with RequestTransactionManager.endRequest and the call from Plc4xProtocolLogic at the stack-trace locations, then reproduce the issue with the BasicTest example using Plc4xServer. Trace how the request enters and leaves runningRequests; done means the test completes without the Unknown Transaction exception and still returns PlcResponseCode.OK.
