SIGINT handler for Linux headless server does not unregister #2555
Description
Describe the bug
Stopping the headless Server should unregister from any Directory with which it is registered. If this is not done, a "ghost entry" remains in the directory list (visible when a client runs with --showallservers or in Jamulus Explorer).
Current behaviour is that the headless Server does not unregister.
To Reproduce
git checkout master
git pull upstream master
make distclean; qmake && make -j3
./Jamulus -s -n -p <openport> -e <Directory server address>
(check the server is visible and operational)
And this shows the log for Jamulus Explorer successfully retrieving the welcome message:

Now shut down the server with Ctrl-C:
^COnHandledSignal: 2
The signal is handled but the Server doesn't send an unregister request, leaving a ghost entry:
Note the "Ping", "Version" and "OS" are not now listed.
Expected behavior
Stopping the headless server should send an unregister request. This does happen when using the UI:
