This issue was brought back by a somewhat recent change to fix slow
shutdown times in Linux.
To paraphrase tfo from the OBS Discord:
"I think the issue is that all the tray actions are parented to
trayIcon, so when it's deleted, Qt auto deletes them as children, then
delete trayMenu on the next line accesses those dead actions."
We now create the tray menu first, then setting the parent of the
actions (show / hide, stop / start streaming, etc.) to the tray menu.
