[Mon] Fix service collisions on ecal_mon_gui (5.13)

[mlclark-resideo]

Very simple fix. Adds the service name to the ServiceTreeItem identifier so that different services running on the same host/process with the same methods don't get accidentally de-duped in ecal_mon_gui.

Description

This PR fixes the following bug:

Working example to demonstrate issue

This Python program creates two different eCAL services with the same PID, host, and method name.

import ecal.core.core as ecal_core
import ecal.core.service as ecal_service
import sys, time

def callback():
      pass

ecal_core.initialize(sys.argv, "BugDemo")
server1 = ecal_service.Server("MyService1")
server1.add_method_callback("GetConfig", "string", "string", callback)
server2 = ecal_service.Server("MyService2")
server2.add_method_callback("GetConfig", "string", "string", callback)

try:
    while True:
        time.sleep(1)
except KeyboardInterrupt:
    pass
finally:
    server1.destroy()
    server2.destroy()
    ecal_core.finalize()

Expected behavior

ecal_mon_gui should show both services on the service widget.

Actual behavior

ecal_mon_gui only shows one service (the most recent one):

The fix

This issue occurs because each of these service listings is a ServiceTreeItem, and the Service widget tracks and prunes ServiceTreeItems based on their generated identifier. The identifier currently only includes the PID, host, and method name. This fix adds the service name as well, so that services that only differ in their name still show up separately.

Now both services show up as expected:
